Hint of SUSY in Flavor Anomalies?

May 13, 2021, 2:30 pm
Bhupal Dev, Washington U at St. Louis
The recent results from the Fermilab muon g-2 experiment have caused quite a stir in the community. At the same time, there are persisting hints of lepton flavor universality violation in some rare B-meson decays. Taken at face value, if these anomalies are interpreted as of beyond the Standard Model (BSM) origin, it is conceivable... More »

Probing the Standard Model with flavor physics: an exclusive determination of $|V_{cb}|$ from the $B\to D^\ast\ell\nu$ semileptonic decay at non-zero recoil

A very rich place to look for phenomena to challenge our current understanding of physics is the flavor sector of the Standard Model (SM). In particular, the $V_{cb}$ matrix element of the CKM matrix is the subject of a long standing tension, depending on whether it is determined using inclusive or exclusive methods. On top... More »

Electron-Ion Collider - a Giant CT Scan for Nuclear Femtography

The proton and neutron, known as nucleons, are the fundamental building blocks of all atomic nuclei that make up essentially all the visible matter in the universe, including the stars, the planets, and us. Nucleons have a complex internal structure. Within Quantum Chromodynamics, nucleons emerge as strongly interacting and relativistic bound states of quarks and... More »

Graded Hilbert spaces and quantum distillation in QFT

May 27, 2021, 2:30 pm
Mithat Unsal, North Carolina State U.
I construct various generalizations of partition function in non-supersymmetric theories, including few fairly close to QCD, that do not undergo a phase transition upon circle compactification. This is similar to what happens in supersymmetric index calculations but there it is guaranteed by supersymmetry, and Bose-Fermi grading of Hilbert space. In manifestly non-supersymmetric theories in QM,... More »

Electroweak symmetry in the early universe

June 3, 2021, 2:30 pm
Yikun Wang, U. Chicago
Behavior of the electroweak symmetry and the Higgs thermal history have intriguing implications for matter antimatter asymmetry creation and early universe physics. In this talk, I will present two beyond the Standard Model scenarios resulted in two different early universe paths of the electroweak symmetry. Electroweak phase transition from an electroweak symmetric phase to the... More »

A lattice QCD calculation of the hadronic light-by-light contribution to the magnetic moment of the muon

June 10, 2021, 2:30 pm
Harvey Meyer, University of Mainz
I present a recent calculation of the hadronic light-by-light scattering contribution to the muon g−2 from the up, down, and strange-quark sector directly using lattice QCD. I first describe the methodology based on coordinate-space methods and a pilot calculation at the SU(3)-flavour symmetric point with a pseudoscalar mass of about 420 MeV. The final result... More »
