Early-times Yang-Mills dynamics and the characterization of strongly interacting matter with statistical learning

Published in arXiv, 2023

Hadronic transport coefficients from the linear sigma model at finite temperature

Published in Phys. Rev. C., 2020

We investigate general frameworks for calculating transport coefficients for quasiparticle theories at finite temperature. Hadronic transport coefficients are then computed using the linear sigma model (LSM).
