El reducido nivel de participaci?n de las medianas empresas en el mercado alternativo de valores como fuente de financiamiento para satisfacer sus necesidades de liquidez en el corto plazo

El ?xito del sector empresarial en el Per? depende en gran medida de las diversas fuentes de financiamiento que sus participantes pueden encontrar en el mercado. En este sentido, el brindarles conocimiento de todas las fuentes posibles y educarlos de tal forma que puedan aprovecharlas en alto nivel, es tambi?n labor de los entes reguladores y por ende del Estado. El presente trabajo de investigaci?n expone al MAV (?Mercado Alternativo de Valores?) como una variante del Mercado de Valores, el cual ha sido dise?ado para que las Medianas Empresas exploren una alternativa que antes, por sus condiciones anteriores, le era pr?cticamente inalcanzable. Asimismo, desde las perspectivas de las Medianas Empresas, se busca descubrir el por qu?, desde su creaci?n (2012), el MAV ha tenido tan poca participaci?n a pesar de lo exitoso que han sido los casos registrados. Esta cuesti?n ha sido desarrollada durante el presente documento mediante una investigaci?n exploratoria de tipo cualitativa, con la finalidad de poder realizar recomendaciones en b?squeda de su mayor concurrencia

Measurement of charged particle spectra in minimum-bias events from proton-proton collisions at root s =13 TeV

Pseudorapidity, transverse momentum, and multiplicity distributions are measured in the pseudorapidity range vertical bar eta vertical bar 0.5 GeV in proton-proton collisions at a center-of-mass energy of root s = 13 TeV. Measurements are presented in three different event categories. The most inclusive of the categories corresponds to an inelastic pp data set, while the other two categories are exclusive subsets of the inelastic sample that are either enhanced or depleted in single diffractive dissociation events. The measurements are compared to predictions from Monte Carlo event generators used to describe high-energy hadronic interactions in collider and cosmic-ray physics.Peer reviewe

Search for supersymmetric partners of electrons and muons in proton–proton collisions at s=13TeV

A search for direct production of the supersymmetric (SUSY) partners of electrons or muons is presented in final states with two opposite-charge, same-flavour leptons (electrons and muons), no jets, and large missing transverse momentum. The data sample corresponds to an integrated luminosity of 35.9 fb−1 of proton–proton collisions at s=13TeV, collected with the CMS detector at the LHC in 2016. The search uses the MT2 variable, which generalises the transverse mass for systems with two invisible objects and provides a discrimination against standard model backgrounds containing W bosons. The observed yields are consistent with the expectations from the standard model. The search is interpreted in the context of simplified SUSY models and probes slepton masses up to approximately 290, 400, and 450 GeV, assuming right-handed only, left-handed only, and both right- and left-handed sleptons (mass degenerate selectrons and smuons), and a massless lightest supersymmetric particle. Limits are also set on selectrons and smuons separately. These limits show an improvement on the existing limits of approximately 150 GeV.0info:eu-repo/semantics/publishe

Search for resonant pair production of Higgs bosons decaying to bottom quark-antiquark pairs in proton-proton collisions at 13 TeV

A search for a narrow-width resonance decaying into two Higgs bosons, each decaying into a bottom quark-antiquark pair, is presented. The search is performed using proton-proton collision data corresponding to an integrated luminosity of 35.9 fb$^{-1}$ at $\sqrt{s}=$ 13 TeV recorded by the CMS detector at the LHC. No evidence for such a signal is observed. Upper limits are set on the product of the production cross section for the resonance and the branching fraction for the selected decay mode in the resonance mass range from 260 to 1200 GeV
