Next-to-Next-to-Leading Order QCD Corrections to Higgs Boson Production in Association with two Jets in Vector Boson Fusion

In this thesis the second-order QCD corrections to electroweak production of a Higgs boson in association with two jets through vector boson fusion are considered. This calculation is fully differential in the kinematics of the Higgs boson and of the final state jets. Infrared divergences are regulated using the antenna subtraction method. We detail the implementation of the process in the parton-level Monte Carlo integrator NNLOJET and present inclusive calculations as well as differential distributions for a wide range of observables at different center-of-mass energies

The Gondwana-South America Iapetus margin evolution as recorded by Lower Paleozoic units of western Precordillera, Argentina: The Bonilla Complex, Uspallata

Terrane, accreted to Gondwana South America during Ordovician times. The Bonilla Complex, which represents the southern tip of the Precordillera, is constituted of metasedimentary rocks of internal and external platform environments. Paleocurrents inferred from sedimentary structures indicate provenance from the northeast and southeast (actual coordinates). The limestones of this complex, located in the eastern part of the outcrops, suggest evolution toward a carbonate-dominated Late Neoproterozoic to Cambrian passive margin. Mafic volcanic rocks were emplaced coevally with sedimentation, whereas ultramafic rocks were later tectonically emplaced. Chemical evidence suggests that the protolith of the metasedimentary rocks was derived from an older exhumed felsic basement belonging to an upper continental crust. The most prominent population of detrital zircons (~500- 600 Ma) from the Bonilla Complex support the hypothesis that these rocks are equivalent to those of the Sierras Pampeanas and the northern Patagonia. The most proximal source of the Pampean zircons found in the Bonilla Complex is the Sierras Pampeanas, located immediately to the east (present coordinates). The Bonilla Complex was deposited in an open marine basin considerably earlier (~50 Ma) than the supposed detachment of the Cuyania Terrane from the Ouachita embayment in the Laurentia margin. It is therefore not necessary to invoke the presence of an allochthonous terrane between the Bonilla Complex and the Gondwana margin to explain the 1 Ga zircon populations. Silurian to Devonian deformation was characterized by metamorphism and imbrication within an accretionary prism, the consequence of eastward subduction in the western margin of Gondwana. Therefore, the Bonilla Complex, as well as equivalent units in western Precordillera, was originally deposited as sediments on a continental shelf at the southwestern margin of Gondwana, covering a basement that was already part of the Gondwana continent by Neoproterozoic-Cambrian times.Fil: Gregori, Daniel Alfredo.

Extending MadFlow: device-specific optimization

In this proceedings we demonstrate some advantages of a top-bottom approach in the development of hardware-accelerated code. We start with an autogenerated hardware-agnostic Monte Carlo generator, which is parallelized in the event axis. This allow us to take advantage of the parallelizable nature of Monte Carlo integrals even if we don't have control of the hardware in which the computation will run (i.e., an external cluster). The generic nature of such an implementation can introduce spurious bottlenecks or overheads. Fortunately, said bottlenecks are usually restricted to a subset of operations and not to the whole vectorized program. By identifying the more critical parts of the calculation one can get very efficient code and at the same time minimize the amount of hardware-specific code that needs to be written. We show benchmarks demonstrating how simply reducing the memory footprint of the calculation can increase the performance of a $2 \to 4$ process.Comment: Proceedings ICHEP 2022, 6 page

PDFFlow: parton distribution functions on GPU

We present PDFFlow, a new software for fast evaluation of parton distribution functions (PDFs) designed for platforms with hardware accelerators. PDFs are essential for the calculation of particle physics observables through Monte Carlo simulation techniques. The evaluation of a generic set of PDFs for quarks and gluon at a given momentum fraction and energy scale requires the implementation of interpolation algorithms as introduced for the first time by the LHAPDF project. PDFFlow extends and implements these interpolation algorithms using Google's TensorFlow library providing the capabilities to perform PDF evaluations taking fully advantage of multi-threading CPU and GPU setups. We benchmark the performance of this library on multiple scenarios relevant for the particle physics community.Comment: 8 pages, 7 figures, 2 tables.

Determining probability density functions with adiabatic quantum computing

A reliable determination of probability density functions from data samples is still a relevant topic in scientific applications. In this work we investigate the possibility of defining an algorithm for density function estimation using adiabatic quantum computing. Starting from a sample of a one-dimensional distribution, we define a classical-to-quantum data embedding procedure which maps the empirical cumulative distribution function of the sample into time dependent Hamiltonian using adiabatic quantum evolution. The obtained Hamiltonian is then projected into a quantum circuit using the time evolution operator. Finally, the probability density function of the sample is obtained using quantum hardware differentiation through the parameter shift rule algorithm. We present successful numerical results for predefined known distributions and high-energy physics Monte Carlo simulation samples.Comment: 7 pages, 3 figure

Reseña del libro “El notodo de Lacan. Consistencia lógica, consecuencias clínicas”. Autor: Guy le Gaufey : Buenos Aires: El cuenco de plata. Ediciones literales, 2007- 224 pág.

Lo mismo, lo diferente, lo otro, lo propio, lo idéntico, arsenal lógico requerido para articular la cuestión del sexo dentro del orden discursivo, constituyen al mismo tiempo instrumentos construidos, en su noble atavío filosófico, para controlar esa cuestión. Es posible que se haya pensado lógicamente contra la cuestión sexual. Tal es la hipótesis sostenida por Guy Le Gaufey en El notodo de Lacan, y el punto de partida de una interrogación crítica de las “fórmulas de la sexuación” que ofrecen extensión lógica a la afirmación según la cual “No hay relación sexual”.Facultad de Psicologí
