The technique of “Stochastic Cooling” of phase space of a particle beam, using microwave techniques in the GHz frequency range, has been employed historically in particle colliders, leading to ground-breaking discoveries. ‘Cooling’ increases the probability of interactions in colliding beams, thus enhancing the likelihood of observing rare…

I make a surprising connection between two long-standing problems in higher-spin gravity: (1) locality concerns at the quartic order in perturbation theory, and (2) the physical meaning of the Didenko-Vasiliev "BPS black hole" solution.

I show that the Didenko-Vasiliev solution…

 A high energy muon collider is a unique machine that breaks the traditional energy/precision dichotomy. It provides both an unprecedented reach in energy with a compact ring and a clean environment that allows precise measurements. I will provide an overview of the powerful physics potential of a multi-TeV muon collider, starting from its…

The Higgs boson was discovered in 2012 by the ATLAS and CMS experiments at the world’s most powerful particle collider, the Large Hadron Collider (LHC) in Geneva, Switzerland. This particle plays a unique role in fundamental physics. It gives all of the known elementary particles, including itself, their masses. While we now have a strong…

Probing the Yukawa couplings is paramount to understand the role played by the Higgs boson in the Standard Model. Ten years after the discovery of the Higgs boson, all the Yukawa couplings to the third generation of fermions have been measured. More recently the CMS and ATLAS collaborations claimed the evidence of the…

To date, LHC searches have provided no definitive evidence for physics beyond the Standard Model (BSM). What if we’re looking in the wrong place? Long-lived particles (LLPs) arise from a variety of well-motivated BSM theories. However, they remain weakly constrained at the LHC: most reconstruction algorithms target prompt decays of particles…

   The MicroBooNE experiment was designed primarily to explore the nature of the previously observed low-energy excess in electron neutrino candidates in the MiniBooNE experiment located in the Booster Neutrino Beamline at Fermi National Accelerator Laboratory. Using an 85-ton active volume Liquid Argon Time Projection Chamber (LArTPC) with its…

Abstract: After the discovery of the Higgs boson by the ATLAS and CMS experiments at the Large Hadron Collider (LHC) at CERN in 2012, a new era of studying the properties of this newly discovered particle has begun. Precision measurement of the Higgs boson properties is a golden testbench of…

Abstract: 
Machine Learning methods are extremely powerful but often function as black-box problem solvers, providing improved performance at the expense of clarity. Our work describes a new machine learning approach which translates the strategy of a deep neural network into simple functions that are meaningful and intelligible to the…

Abstract: Probing the Higgs boson coupling to the muon is one of the last experimentally accessible frontiers in the direct measurement of Higgs boson couplings at the LHC. This seminar will highlight the first evidence for the rare Higgs boson decay to muons, achieved by the CMS Collaboration using the full dataset collected at 13 TeV during…
