Title: Dense Relativistic Matter-Antimatter Plasmas.

Short abstract:
Dense relativistic matter-antimatter plasmas, prevalent in extreme  
astrophysical settings and accessible through high-energy particle  
collisions, are explored in this study through a covariant kinetic  
theory incorporating collisional scattering. The research investigates  
the linear responses of electron-positron and quark-gluon plasmas to  
electromagnetic fields, revealing mechanisms like dynamic damping and  
screening. Key findings include an analytic formula for magnetic field  
evolution in quark-gluon plasmas during heavy ion collisions,  
potentially aiding in experimental conductivity measurements, and a  
quantified enhancement of nuclear reaction rates during Big Bang  
Nucleosynthesis due to damped-dynamic screening, representing a minor  
but notable correction to conventional BBN models.

Everyone is welcome to attend.
