2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/82529I calculate the dispersion relation for quarks of mass $m$ and momentum $k$ in a quark gluon plasma at temperature $T$, in the limit $m^2+k^2 \gg (gT)^2$, where $g$ is the strong coupling constant. I find three contributions to the dispersion relation: one that depends on $T$ but not $m$ or $k$, one that depends on $m$ and $T$ but not $k$, and third contribution that depends on all three (and is opposite in sign to the other two).latex, 5 pages, CERN-TH.7034/93Nuclear TheoryHigh Energy Physics - Phenomenologytext
