HET Seminar | Si Li, IAS; Tsinghua University | “Deforming Holomorphic Chern-Simons at Large N” | Bloomberg Lecture Hall
Fri, Nov 15, 2019, 1:45 pm

We describe the coupling of holomorphic Chern-Simons theory at large N with Kodaira-Spencer gravity. This gives a complete description of open-closed string field theory in the topological B-model. We explain an anomaly cancellation mechanism at all loops in perturbation theory in this model.

HET Seminar | Andrew Turner, MIT | "General F-theory Models with SU(3) x SU(2) x U(1) / Z_6 Symmetry” | Bloomberg Lecture Hall
Mon, Sep 30, 2019, 2:30 pm

We construct a general form for an F-theory Weierstrass model over any base giving a 6D or 4D supergravity theory with gauge group SU(3) x SU(2) x U(1) / Z_6 and associated generic matter. The concept of 'generic matter' can be rigorously defined in 6D supergravity and generalizes naturally to four dimensions for F-theory models.

HET Seminar | Amit Sever, CERN | "The Holographic Dual of Strongly γ-deformed N=4 SYM Theory" | Bloomberg Lecture Hall
Mon, Sep 16, 2019, 2:30 pm

We present a first-principles derivation of a weak-strong duality between the four-dimensional fishnet theory in the planar limit and a discretized string-like model living in AdS5. At strong coupling, the dual description becomes classical and we demonstrate explicitly the classical integrability of the model.

HEP Seminar-Oskar Hartbrich-University of Hawaii-"Belle II - First Collisions in a New Particle Physics Experiment at the Intensity Frontier
Wed, Jan 9, 2019, 2:00 pm to 3:30 pm

Abstract
The B factory experiment Belle at the KEKB collider at KEK (Tsukuba, Japan) was built to experimentally investigate CP violation in the B system. Belle and BaBar ultimately confirmed large mixing induced CP violation, leading to the 2008 Nobel Prize in Physics for Kobayashi and Maskawa.

High Energy Physics Experimental Seminar-Livia Soffi-"Unvealing New Physics with Photons at LHc CMS Experiment", Jadwin 303
Mon, Sep 25, 2017, 4:00 pm

Since the discovery of the Higgs boson in 2012, the experimental program at the LHC has started to explore previously unreachable kinematical regimes, where potentially new heavy particles can be produced. The ATLAS and CMS ex- periments can search for new physics in a wide range of final states with the highest sensitivity to date.
