英文摘要: In this paper, we calculate the transverse momentum diffusion coefficient k(T) of heavy quark and gluon penetration length in the deconfinement phase of Sakai-Sugimoto model, which is known as a holographic dual of large N-c QCD. We find that for the heavy quark moving through the thermal plasma with a constant velocity upsilon < 1, the transverse momentum diffusion coefficient k(T) alpha lambda gamma T-1/3(4)/T-d, and the gluon penetration length Delta x alpha (E) over cap (2/5). These results are different from those calculated in N = 4 super-Yang-Mills theory, which are k(T) alpha lambda gamma T-1/2(3) and Delta x alpha (E) over cap (1/3), respectively. In the high energy limit, the difference between the two pairs of results should be evident, so we hope that the future LHC experiments can tell us which model is more closely related to the realistic strongly coupled QCD at finite temperature.
