    “…Further, we examine the existence of long lived gluino that manifests one of the major consequences of mu-split SUSY scenario, by computing its decay width as well as lifetime corresponding to the 3-body decays of the gluino into a quark, a squark and a neutralino or Goldstino, as well as 2-body decays of the gluino into either a neutralino or a Goldstino and a gluon. …”

    “…Events with muons in the final state are an important signature for many physics topics at Large Hadron Collider (LHC), for instance, searches for Higgs boson production or new phenomena, measurements on the standard model processes like top-quark, W, Z production. Thus, efficient trigger on muons in data taking and understanding its performance are crucial to perform these physics studies. …”

    “…Measuring the highest energy density ever produced in nucleus-nucleus collisions, the detector has been designed to study the properties of the created hot and dense medium, assumed to be a Quark-Gluon Plasma. Comprised of 18 high granularity sub-detectors, ALICE delivers data from a few million electronic channels of proton-proton and heavy-ion collisions. …”

    “…The full recorded data sample will be used by physicists to search for New Physics and precise measurement of CP-violation in heavy flavor quark sector. Despite its superb performance it is clear that the LHCb experiment is statistically limited for a number of important decay channels (such as $B_d \to K^*\mu \mu$ or $B_s \to \phi \phi$ ). …”

    “…The latter are still large due to the limited statistics, and could very well accommodate the possible new physics effects as seen in other rare B decays with b-to-s quark transitions. Future studies of the recently measured $B_s\rightarrow \mu^+ \mu^-$ and $B^0 \rightarrow \mu^+ \mu^-$ decays are eagerly awaited. …”

    Publicado 2016
    “…The jet charge is sensitive to the electric charge of the parton initiating a jet and the number of charged particles within a jet provides a powerful means to distinguish gluon­initiated from quark­initiated jets. These quantities were measured by the ATLAS collaboration using a selection of di­jet events in 20.3 /fb of data collected at a center­of­mass energy of 8 TeV. …”
