Abstract: Observation of lepton flavor violation (LFV) in the current round of experiments would provide an unambiguous sign of New Physics. All models of LFV New Physics can be encoded in a low energy effective Lagrangian that contains over a dozen distinct operator structures. I will discuss how to constrain Wilson coefficients of those operators from the data obtained in various LFV leptonic and radiative leptonic transitions of B/D/K mesons, LFV decays of various quarkonia, as well as from LHC. About the speaker: Alexey A Petrov is an American physicist known for his theoretical research in the area of physics of heavy quarks. Currently, he is a Professor of Physics at Wayne State University. Alexey Petrov graduated from the Peter the Great St. Petersburg Polytechnic University in Saint Petersburg, Russia, with a Diploma in physics in 1994. In 1997, he graduated from the University of Massachusetts Amherst, with a Doctor of Philosophy in theoretical physics under the direction of John F. Donoghue. He went on to do postdoctoral research at Johns Hopkins University (1997-2000), and Cornell University (2000-2001) before joining the faculty of Wayne State University in 2001. Petrov received National Science Foundation CAREER Award in 2005. He was elected a Fellow of the American Physical Society in 2015 “for contributions to heavy flavor physics, in particular studies of charm quarks and contributions to indirect searches for physics beyond the Standard Model.” [2] He was among the first professors to be awarded a Comenius Guest Professorship (2015–16) at the University of Siegen in Siegen, Germany.[3]
