Emily Ann Thompson (DESY) “The Quest For Long-Lived Particles: Searching For Displaced Vertices and Tracking in the Trigger”

Zoom Talk 50A-5132, Berkeley, ca

Abstract: The existence of long-lived particles (LLPs) is a common feature in many theories beyond the Standard Model. For example, models with small couplings (i.e. R-parity-violating supersymmetry) and models with compressed mass spectra (i.e. co-annihilating dark matter) predict the presence …

Dominique Trischuk (University of British Columbia) “Displaced Vertex Search for Heavy Neutral Leptons with the ATLAS Detector”

Zoom Talk 50A-5132, Berkeley, ca

Abstract:  This seminar will present recent results of a search for long-lived heavy neutral leptons (HNLs) in proton-protoncollisions at the Large Hadron Collider (LHC). The Standard Model (SM) of particle physics is an extremely successful theory and its major predictions have …

Oliver H.E. Philcox (Princeton) ” Large Scale Structure Beyond the 2-Point Function”

Zoom Talk 50A-5132, Berkeley, ca

Abstract: Quantum fluctuations in inflation provide the seeds for the large scale distribution of matter today. According to the standard paradigm, these fluctuations induce density perturbations that are Gaussian distributed. In this limit, all the information is contained within the …

Robin Hayes (University of British Columbia; Canada) “Probing the Standard Model Through Measurements of the Higgs Boson with the ATLAS Detector”

Zoom Talk 50A-5132, Berkeley, ca

Abstract: As the most recently-discovered particle of the Standard Model (SM), the Higgs boson plays a key role in the quest to deepen our understanding of fundamental physics. Measurements of its production cross-sections probe for disagreement with the SM that …

Boryana Hadzhiyska (Harvard) “Uncovering physics from Stage-IV cosmological experiments with accurate galaxy models”

Zoom Talk 50A-5132, Berkeley, ca

Abstract: Over the next few years, cutting-edge cosmological experiments such as DESI, Rubin and CMB-S4 will provide an exquisite probe of the accelerated expansion of the Universe, structure formation, and general relativity, and thus bring us closer to revealing the nature …

Brendon Aurele Bullard (Harvard) “Toward Precision Measurements of the Higgs Yukawa Couplings” 

Zoom Talk 50A-5132, Berkeley, ca

Abstract: With the discovery of the Higgs boson in 2012, high energy physics has entered an era in which all fundamental particles predicted by the Standard Model have been observed. With no conclusive observations of physics beyond the Standard Model, precision tests …

Maria Mironova (Oxford) “First Direct Constraint on the Higgs-Charm Coupling and its Expected Evolution with the ATLAS Detector Upgrade”

Zoom Talk 50A-5132, Berkeley, ca

Abstract:
 The coupling of the Higgsboson to charm quarks has eluded experimental observation since the Higgs boson discovery in 2012. At present, this is the largest contribution to possibleHiggs boson decays that is not experimentally verified. However, this measurement is …

Vetri Velan (UC Berkeley) “The Present and Future of Dark Matter Direct Detection”

Zoom Talk 50A-5132, Berkeley, ca

Abstract:
  Dark matter is one of the primary unsolved problems in modern particle physics. Since the late 1980s, physicists have been trying to directly detect dark matter particles passing through the Earth, typically by searching for nuclear recoils. This search …

Field Rose Rogers (MIT) “The GAPS Antarctic Balloon Experiment: Low-energy Antinuclei for Dark Matter Detection”

Abstract:  Despite overwhelming evidence of abundant dark matter in the Universe, the nature of this material remains a mystery. The General Antiparticle Spectrometer (GAPS) is an upcoming NASA Antarctic balloon mission to search for signatures of dark matter annihilation or …
