| 14:00 - 15:00 Weekly Seminar HEPCo Group Quantum Critical Higgs: from AdS5 to colliders School PHYSICS Abstract: Quantum Critical Higgs (QCH) are a set of models where the Higgs sector is tuned close to an IR critical point, at which the theory is conformal. The set of models that goes under this name is large; it is usually assumed that the conformal theory is strongly coupled. In this talk I will follow our work in Arxiv: 1908.06186 . I will explore two scenarios by analyzing their weakly coupled duals via AdS/CFT correspondence. I will further examine the signature of the new physics in hadron colliders. Date: Tuesday, 18 August 2 p.m. - 3 p.m. Skyroom ... 17:30 - 18:30 Mathematics Colloquium Lyapunov exponents School MATHEMATICS The concept of Lyapunov exponent goes back to Lyapunov's 1892 thesis on the stability of differential equations, and has numerous applications in various branches of mathematics and science. Starting from the 1960s, it found its proper mathematical framework in ergodic theory, where it has had a prominent role ever since. In this colloquium lecture I will review a few recent developments, especially about the way Lyapunov exponents depend on the underlying dynamical system.

Most interestingly, they can trigger quantum anomalous processes leading to unusual charged-particle correlations in the observable data. The direct verification of the corresponding theoretical prediction is, however, complicated by a large uncertainty in the magnetic field produced in collisions. To constrain the uncertainty, one needs an independent measurement of the field. The direct photon emission could potentially provide such a measurement. In this talk, the recent first-principle calculations of the direc ... |
