Abstract: The discovered XYZ exotic hadronic states with two heavy quarks constitute one of the most important open problems in strong interaction theory. In this talk, I show that an effective field theory derived from QCD, the Born Oppenheimer effective field theory (BOEFT), can describe exotics of any composition. I show the results of the coupled Schrödinger equations that describe hybrids, tetraquarks, pentaquarks, doubly heavy baryons, and quarkonia at leading order, including also nonadiabatic…

Abstract: Neutrino decay is governed by a non-Hermitian effective Hamiltonian and in general the mass eigenstates and decay eigenstates are not the same. This mismatch is inevitable in the presence of matter and the Hermitian and anti-Hermitian components cannot be simultaneously diagonalized by unitary transformations for all matter densities. In this talk a formalism for treating the two-flavor neutrino propagation through matter of uniform density, for neutrino decay to invisible states, will be…

Abstract: Feynman integrals are crucial ingredients for calculations within quantum field theory. A new tool for their investigation comes with the recent discovery of integrable structures for large families of Feynman graphs and the associated symmetry constraints. These constraints can be formulated in terms of the Yangian algebra and result in differential equations for the considered integrals. Here we review the Yangian symmetry of Feynman integrals and its connection to AdS/CFT integrability via…

Abstract: In 2024, the HERA workshop series, which is supported by the Wilhelm and Else Heraeus Foundation, will carry on with its mission by organizing the next workshop in Athens, Greece. These workshops serve as a platform for early career scientists to receive training, engage in interactive discussions, conceptualize research projects, broaden their perspectives, and initiate international collaborations. The second workshop in this series is scheduled for the week of September 15th - 20th, 2024,…
