    Publicado 2016
    “…One of those detectors is the LHCb experiment which was specifically designed for the study of heavy hadrons containing bottom and charm quarks (heavy flavour physics). To deal with the increased beam energy and instantaneous luminosity of the LHC after the Long Shutdown 2 in 2018/19, several subsystems of the LHCb detector have to be exchanged and upgraded. …”

    “…Another challenge is to exploit the increased signal rate that results from removing the 1 MHz readout bottleneck, combined with the higher instantaneous luminosity. Many charm hadron signals can be recorded at up to 50 times higher rate. …”

    “…This thesis presents two measurements performed with the ALICE detector at the CERN Large Hadron Collider (LHC). Charm jets were tagged using D$^0$ mesons. Their cross section and fragmentation function in \pp\ collisions at the center-of-mass energy $\sqrt{s}=7$~TeV were measured and compared with theoretical predictions obtained with Monte Carlo generators based on QCD. …”

    “…Recent STAR measurements indicate that in Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}=$ 200 GeV $D^{0}$ mesons develop large $v_{2}$ similarly as light-favor hadrons, implying that charm quarks interact strongly with the thermalized medium at the top RHIC energy. …”

    “…The Higgs boson transverse momentum differential cross-section distributions are used to constrain the charm Yukawa coupling modifier (95% confidence level interval on $\kappa_c$ of $[-12, 11]$ in the $H \to 4\ell$ analysis and of $[-19, 24]$ in the $H \to \gamma\gamma$ analysis). …”

    “…Furthermore, the channels associated with heavy quark (charm and beauty) production could be studied. As a feasibility study, we performed a test run in 2018 at the proposed detector location with a 30-kg lead/tungsten emulsion detector and collected data of 12.5 fb$^{-1}$. …”

    “…After passing both magnetic septa SMH57 and SMH61 in the PS, the beam enters the F61 transfer line that transports the beam either to the so-called North Targets via the lines F62 and F63 or towards T08, which serves the irradiation facilities IRRAD and CHARM. During operation of primary ion beams, only these irradiation facilities can be operated. …”

    “…The availability of computing resources is a limiting factor in data collection at the LHCb experiment, due to the high production rate of beauty and charm hadrons. For Run 2, LHCb has implemented a novel approach to make optimal use of these resources: the output of the first software trigger stage is buffered to disk and the second stage is executed asynchronously, using 100\% of the available trigger farm even between LHC fills. …”
