Cuerpo, sexo y derecho: ¿la ciencia como la última palabra?

La ponencia que presento se inscribe en el marco de una investigación mayor realizada con apoyo del CONICET y del Proyecto BID- PICT 2008-1145 sobre Intersecciones y cruces entre experiencias subjetivas y discursos sociopolíticos sobre derechos sexuales y reproductivos. En este caso, se trata de problematizar cómo, crecientemente, el discurso científico aparece en los debates sobre sexualidad, salud y derechos como si fuera la última palabra, la última ratio donde toda aseveración sobre el tema adquiriría legitimidad. En Argentina, los debates en torno de los derechos sexuales, reproductivos y no reproductivos ingresaron en la agenda pública y política hacia los años noventa. Desde entonces han ido sufriendo una torsión a favor una creciente medicalización primero y luego una llamativa judicialización, particularmente la cuestión del aborto. Esto aparece en los debates, por un lado, como una profusión de argumentos en relación con el aspecto sanitario de la sexualidad bajo la lógica de la demanda individual en detrimento de la colectiva. Por el otro, se produce un desplazamiento desde el eje de la libertad a decidir en torno de la sexualidad/ la reproducción al eje de la igualdad socioeconómica. Y , por último, se genera un movimiento que tiende a centrarse sobre el aspecto legal del debate y que apunta a traducir argumentos políticos en científicos a fin de dotarlos de una supuesta objetividad y neutralidad capaz de zanjar el debate político que pone en juego posiciones éticas, morales, religiosas, ideológicas, etcétera. Enfocada sobre esos ejes de debate, me abocaré a describir y analizar las oportunidades y los riesgos de torcer el debate sobre derechos (no) reproductivos y sexuales desde el terreno político al terreno científico en clave legal o médico-sanitarista tomando como fuente principal un caso concreto: el debate público convocado por la Comisión de Salud de la Legislatura de la Ciudad de Buenos Aires entre octubre y noviembre de 2008, una serie de cuatro reuniones en la que se evaluaban procedimientos para hacer viables los abortos no punibles en los casos previstos por el Código Penal. Para acercarme a mi objetivo usaré como fuente principal las versiones taquigráficas de esos debates en la Comisión de Salud de la Legislatura de la Ciudad de Buenos Aires que tuvieron lugar en octubre y noviembre del 2008 (AAVV, 2008 a, b, c, d). Para cada una de esas sesiones se invitaron a panelistas invitados/as, así como hubo un momento abierto al público. Fue la oportunidad para escuchar diversas opiniones desde múltiples campos de acción: la ciudadanía, los y las expertos médicas/os y abogadas/os, representantes de la sociedad civil, funcionarios/as, etcétera.Eje 12: Mujeres y justiciaFacultad de Humanidades y Ciencias de la Educació

MUSiC : a model-unspecific search for new physics in proton-proton collisions at root s=13TeV

Results of the Model Unspecific Search in CMS (MUSiC), using proton-proton collision data recorded at the LHC at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1), are presented. The MUSiC analysis searches for anomalies that could be signatures of physics beyond the standard model. The analysis is based on the comparison of observed data with the standard model prediction, as determined from simulation, in several hundred final states and multiple kinematic distributions. Events containing at least one electron or muon are classified based on their final state topology, and an automated search algorithm surveys the observed data for deviations from the prediction. The sensitivity of the search is validated using multiple methods. No significant deviations from the predictions have been observed. For a wide range of final state topologies, agreement is found between the data and the standard model simulation. This analysis complements dedicated search analyses by significantly expanding the range of final states covered using a model independent approach with the largest data set to date to probe phase space regions beyond the reach of previous general searches.Peer reviewe

Measurement of prompt open-charm production cross sections in proton-proton collisions at root s=13 TeV

The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb(-1). The differential production cross sections of the D*(+/-), D-+/-, and D-0 ((D) over bar (0)) mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p(T) < 100 GeV and vertical bar eta vertical bar < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.Peer reviewe

Development and validation of HERWIG 7 tunes from CMS underlying-event measurements

This paper presents new sets of parameters (“tunes”) for the underlying-event model of the HERWIG7 event generator. These parameters control the description of multiple-parton interactions (MPI) and colour reconnection in HERWIG7, and are obtained from a fit to minimum-bias data collected by the CMS experiment at s=0.9, 7, and 13Te. The tunes are based on the NNPDF 3.1 next-to-next-to-leading-order parton distribution function (PDF) set for the parton shower, and either a leading-order or next-to-next-to-leading-order PDF set for the simulation of MPI and the beam remnants. Predictions utilizing the tunes are produced for event shape observables in electron-positron collisions, and for minimum-bias, inclusive jet, top quark pair, and Z and W boson events in proton-proton collisions, and are compared with data. Each of the new tunes describes the data at a reasonable level, and the tunes using a leading-order PDF for the simulation of MPI provide the best description of the dat

Reconstruction of signal amplitudes in the CMS electromagnetic calorimeter in the presence of overlapping proton-proton interactions

A template fitting technique for reconstructing the amplitude of signals produced by the lead tungstate crystals of the CMS electromagnetic calorimeter is described. This novel approach is designed to suppress the contribution to the signal of the increased number of out-of-time interactions per beam crossing following the reduction of the accelerator bunch spacing from 50 to 25 ns at the start of Run 2 of the LHC. Execution of the algorithm is sufficiently fast for it to be employed in the CMS high-level trigger. It is also used in the offline event reconstruction. Results obtained from simulations and from Run 2 collision data (2015-2018) demonstrate a substantial improvement in the energy resolution of the calorimeter over a range of energies extending from a few GeV to several tens of GeV.Peer reviewe

Observation of the Production of Three Massive Gauge Bosons at root s=13 TeV

The first observation is reported of the combined production of three massive gauge bosons (VVV with V = W, Z) in proton-proton collisions at a center-of-mass energy of 13 TeV. The analysis is based on a data sample recorded by the CMS experiment at the CERN LHC corresponding to an integrated luminosity of 137 fb(-1). The searches for individualWWW, WWZ, WZZ, and ZZZ production are performed in final states with three, four, five, and six leptons (electrons or muons), or with two same-sign leptons plus one or two jets. The observed (expected) significance of the combinedVVV production signal is 5.7 (5.9) standard deviations and the corresponding measured cross section relative to the standard model prediction is 1.02(-0.23)(+0.26). The significances of the individual WWW and WWZ production are 3.3 and 3.4 standard deviations, respectively. Measured production cross sections for the individual triboson processes are also reported

Search for dark photons in Higgs boson production via vector boson fusion in proton-proton collisions at √s = 13 TeV

A search is presented for a Higgs boson that is produced via vector boson fusion and that decays to an undetected particle and an isolated photon. The search is performed by the CMS collaboration at the LHC, using a data set corresponding to an integrated luminosity of 130 fb−1, recorded at a center-of-mass energy of 13 TeV in 2016–2018. No significant excess of events above the expectation from the standard model background is found. The results are interpreted in the context of a theoretical model in which the undetected particle is a massless dark photon. An upper limit is set on the product of the cross section for production via vector boson fusion and the branching fraction for such a Higgs boson decay, as a function of the Higgs boson mass. For a Higgs boson mass of 125 GeV, assuming the standard model production rates, the observed (expected) 95% confidence level upper limit on the branching fraction is 3.5 (2.8)%. This is the first search for such decays in the vector boson fusion channel. Combination with a previous search for Higgs bosons produced in association with a Z boson results in an observed (expected) upper limit on the branching fraction of 2.9 (2.1)% at 95% confidence level

Search for a light pseudoscalar Higgs boson in the boosted mu mu tau tau final state in proton-proton collisions at root s=13 TeV

A search for a light pseudoscalar Higgs boson (a) decaying from the 125 GeV (or a heavier) scalar Higgs boson (H) is performed using the 2016 LHC proton-proton collision data at root s = 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1), collected by the CMS experiment. The analysis considers gluon fusion and vector boson fusion production of the H, followed by the decay H -> aa -> mu mu tau tau, and considers pseudoscalar masses in the range 3.6 aa -> mu mu tau tau, down to 1.5 (2.0)x10(-4) for m(H) = 125 (300) GeV. Model-dependent limits on B(H -> aa) are set within the context of two Higgs doublets plus singlet models, with the most stringent results obtained for Type-III models. These results extend current LHC searches for heavier a bosons that decay to resolved lepton pairs and provide the first such bounds for an H boson with a mass above 125 GeV.Peer reviewe
