  3. 319. Probing the nature of electroweak symmetry breaking with Higgs boson pair-production at ATLAS
    Maximilian J Swiatlowski (TRIUMF (CA))
    21/02/2022, 09:45

    In the Standard Model, the ground state of the Higgs field is not found at zero but instead corresponds to one of the degenerate solutions minimising the Higgs potential. In turn, this spontaneous electroweak symmetry breaking provides a mechanism for the mass generation of nearly all fundamental particles. The Standard Model makes a definite prediction for the Higgs boson self-coupling and...

  4. 321. Searches for resonances decaying to pairs of heavy bosons in ATLAS
    Fang-Ying Tsai (Stony Brook University (US))
    21/02/2022, 10:00

    Many new physics models predict the existence of Higgs-like particles decaying into two bosons (W, Z, photon, or Higgs bosons) making these important signatures in the search for new physics. Searches for Vγ, VV, and VH resonances have been performed in various final states. In some of these searches, jet substructure techniques are used to disentangle the hadronic decay products in highly...

  6. 323. Measurements of associated top quark production and searches for new top-quark phenomena with the ATLAS detector
    Nedaa Alexandra Asbah (Harvard University (US))
    21/02/2022, 10:45

    The high center-of-mass energy of proton-proton collisions and the high integrated luminosities at the CERN Large Hadron Collider make it possible to study rare processes of the Standard Model (SM) with unprecedented precision and search for new physics that might enhance extremely rare processes in the SM. Measurements of rare SM processes provide new tests of the SM predictions with the...

  7. 322. Measurement of the charge asymmetry in highly boosted top-quark pair production in pp collision data collected by the CMS experiment
    Hugo Alberto Becerril Gonzalez (University of Illinois at Chicago (US))
    21/02/2022, 11:00

    Due to interference between particles involved in the production of top quark pairs in hadron collisions, top quarks are produced preferentially in the center of the LHC’s collisions, while antitop quarks are produced preferentially at larger angles. This central–forward charge asymmetry can be altered by several BSM processes. In this report, we will discuss the measurement of the charge...

  8. 325. Searches for BSM physics using challenging and long-lived signatures with the ATLAS detector
    Jyoti Prakash Biswal (University of Alberta (CA))
    21/02/2022, 11:15

    Various theories beyond the Standard Model predict new, long-lived particles with unique signatures which are difficult to reconstruct and for which estimating the background rates is also a challenge. Signatures from displaced and/or delayed decays anywhere from the inner detector to the muon spectrometer, as well as those of new particles with fractional or multiple values of the charge of...

  9. 317. Track Reconstruction at Level-1 in CMS for HL-LHC
    Derek James Cranshaw (Cornell University (US))
    21/02/2022, 11:30

    With the planned high-luminosity upgrade of the LHC increasing the number of simultaneous collisions per bunch crossing by at least a factor of four, the experiments at the LHC will need new handles to keep the trigger rate at manageable levels. To this end, the CMS detector plans to incorporate tracking information as part of its Level-1 trigger system for the phase 2 upgrade. We present here...

  10. 316. Performing precision measurements and new physics searches at the HL-LHC with the upgraded CMS Level-1 Trigger
    Jona Motta (LLR, École Polytechnique (FR))
    21/02/2022, 16:45

    The High-Luminosity LHC will open an unprecedented window on the weak-scale nature of the universe, providing high-precision measurements of the standard model as well as searches for new physics beyond the standard model. Such precision measurements and searches require information-rich datasets with a statistical power that matches the high-luminosity provided by the Phase-2 upgrade of the...

  11. 353. Search for new physics using top quark pairs produced in association with a boosted Z or Higgs boson in effective field theory
    Bryan Caraway (Baylor University (US))
    21/02/2022, 17:00

    A data sample containing top quark pairs produced in association with a boosted \PZ or Higgs boson is used to search for signs of new physics within the framework of effective field theory (EFT). The data correspond to an integrated luminosity of $138\fbinv$ of proton-proton collisions produced at a center-of-mass energy of 13 TeV at the LHC and collected by the CMS experiment. Selected...

  12. 327. Searches for strong production of supersymmetric particles with the ATLAS detector
    Arka Santra (Weizmann Institute of Science (IL))
    21/02/2022, 17:15

    Supersymmetry is one of the best motivated and studied Standard Model (SM) extensions, thanks to its elegant solutions to several aspects not addressed by the SM. Naturalness arguments for weak-scale supersymmetry allow supersymmetric partners of the gluons and third generation quarks with masses light enough to be produced at the LHC. The latest results of searches conducted by the ATLAS...

  13. 328. Searches for R-parity violating Supersymmetry with the ATLAS Experiment
    Hoang Dai Nghia Nguyen (Université de Montreal (CA))
    21/02/2022, 17:30

    R-parity violating (RPV) Supersymmetry (SUSY) is one of the least constrained SUSY scenarios, despite being well theoretically motivated. The ATLAS Experiment is exploiting the full-Run-2 dataset to carry out searches for RPV SUSY and close the remaining gaps, and in this talk we present on overview of the recent public results targeting this scenario.

    Bertrand Echenard (California Institute of Technology (US))
    22/02/2022, 10:00

    Elucidating the nature of dark matter remains a central challenge in fundamental physics. A growing interest in light (sub-GeV) dark matter consisting of new particles coupling only feebly to ordinary matter has emerged over the last decade. Low-energy, high luminosity colliders experiments, such as BABAR, are ideally suited to probe these possibilities. In this talk, we will review the...

  62. 312. Search for exotic decays of the Higgs boson and additional scalar particles in ATLAS
    Christopher Robyn Hayes (University of Michigan (US))
    24/02/2022, 19:30

    The discovery of the Higgs boson with the mass of about 125 GeV completed the particle content predicted by the Standard Model. Even though this model is well established and consistent with many measurements, it is not capable to solely explain some observations. Many extensions of the Standard Model addressing such shortcomings introduce additional Higgs-like bosons which can be either...

  63. 320. Search for rare and lepton flavor violating decays of the Higgs boson with the ATLAS detector
    Gianantonio Pezzullo (Yale University)
    24/02/2022, 19:45

    The Standard Model predicts several rare Higgs boson decay channels, among which are the decays to a Z boson and a photon, to a low-mass lepton pair and a photon, and to a meson and photon. The observation of some of these decays could open the possibility of studying the CP and coupling properties of the Higgs boson in a complementary way to other analyses. In addition,...

    Many theories beyond the Standard Model predict new phenomena, such as heavy vectors or scalar, and vector-like quarks, in final states containing bottom or top quarks. Such final states offer great potential to reduce the Standard Model background, although with significant challenges in reconstructing and identifying the decay products and modelling the remaining background. The recent 13...
