    The ATLAS New Small Wheels (NSW) Phase I Muon System upgrade will use Micromegas and small-strip Thin Gap Chambers (sTGC) as both trigger and precision tracking detectors. A new ASIC, the VMM, is being developed for the front end of both detector technologies. The VMM is a sophisticated ASIC, System on Chip (SOC), providing digitized amplitude and time information as well as independent...

    The ATLAS experiment at the LHC is planning a second phase of upgrades to prepare for the "High
    Luminosity LHC", a 4th major run due to start in 2026. In order to deliver an order of magnitude more data than
    previous runs, 14 TeV protons will collide with an instantaneous luminosity of 7.5 × 1034 cm−2s−1, resulting
    in much higher pileup and data rates than the current experiment was...

    The measurement of Higgs pair production will be a cornerstone of the LHC program in the coming years. Double Higgs production provides a crucial window upon the mechanism of electroweak symmetry breaking and has a unique sensitivity to the Higgs trilinear coupling. We study the feasibility of a measurement of Higgs pair production in the bbbb final state at the LHC. Our analysis is based on a...

    The Drell-Yan (DY) process stands for a unique probe to testing initial-state effects that is not accompanied with any final state interaction, either energy loss or absorption. Moreover, the measured DY dilepton pair mass allows to investigate different kinematical regions where coherence or non-coherent effects are expected only. For this purpose, we used the color dipole approach where for...

    We investigate the renormalization group running of gauge couplings in various radiative neutrino mass models, which generate neutrino masses at one- and two-loop order. We discuss the possibility for these couplings to unify in such models at an energy scale close to the GUT scale. The studies are performed both analytically, at one-loop level, and numerically, at two-loop level, using the...

    We present measurements of the differential production cross section of B hadron in pp collisions at a center-of-mass energy of 13 TeV. The data sample used in this study was collected by the CMS experiment in 2015 , with a bunch spacing of 25ns, it corresponds to an integrated luminosity of 2.71 fb-1. These measurements are important tools to investigate heavy-quark production mechanisms in QCD.

    The lack of conclusive evidence for new physics in Run I of the LHC suggests that future discoveries may manifest themselves with small numbers of signal events. In this case, it will be crucial to use analysis techniques that extract as much information as possible from a limited number of events. Previously, a technique exploiting correlations in the full multi-particle phase space to...

    In the previous efforts, we constructed N-Body systems based on non-temporal and nonlinear extension of Lorentz transformation. In this construction, we rely only on two parameters, nonlinear degree and normalized momentum to characterize the systems. We then explored root computation via iteration in the context of dynamical systems. The solution sets demonstrate various forms similar to...
