We derive differential equations from path-integral based non-equilibrium quantum field theory, that cover the dynamics and spectrum of non-relativistic two-body fields for any environment. For concreteness of the two-body fields, we choose the full potential non-relativistic Quantum Electrodynamics Lagrangian in this work. After closing the correlation function hierarchy of these equations...
Quarkonium suppression is one of the probes of the formation of a quark-gluon plasma in heavy-ion collisions. Three phenomena influence the evolution of quarkonium in a medium: screening, collisions with medium partons and recombination. A formalism in which all these mechanisms can be described consistently is that of open quantum system. In this talk, I will review how to combine the open...
Quantifying the transport properties of heavy particles traveling through thermal non-abelian plasmas is of paramount importance to interpret measurements on those particles conducted after the freezeout. One such example is quarkonium suppression in heavy-ion collisions (HIC). To explain the experimental data and extract physical quantities encoding the properties of the QGP, a solid...
This talk approaches electroweak WIMP annihilation from the perspective of the EFT for quarkonium annhilation. After discussing the similarities and differences, I cover next-to-leading order corrections to the potential between static sources with SU(2) x U(1) charge after electroweak symmetry breaking and their impact on the computation of the Sommerfeld-corrected dark matter relic density....
