Excitations in Hot Non-Commutative Theories

We study the dispersion relation for scalar excitations in supersymmetric, noncommutative theories at finite temperature. In N =4 Yang-Mills the low momenta modes have superluminous group velocity. In the massless Wess-Zumino model the minimum of the dispersion relation is at non zero momentum for temperatures above T0 ≈ (gθ) 1 2 . We briefly comment on N… CONTINUE READING
