Quark Energy Loss

AbstractWe study the effect of back reaction on the energy loss of light quarks in strongly coupled $${\mathcal {N}}=4$$ N = 4 supersymmetric Yang–Mills (SYM) plasma, by using the AdS/CFT correspondence. We perform the analysis within falling string and shooting string approaches, respectively. It is shown that the back reaction, arising from the presence of static heavy quarks uniformly distributed over SYM, enhances the energy loss, in agreement with the findings of the drag force and jet quenching parameter.

AbstractPlasma dynamics critically depends on density and temperature, thus well-controlled experimental realizations are essential benchmarks for theoretical models. The formation of an ultracold plasma can be triggered by ionizing a tunable number of atoms in a micrometer-sized volume of a 87Rb Bose-Einstein condensate (BEC) by a single femtosecond laser pulse. The large density combined with the low temperature of the BEC give rise to an initially strongly coupled plasma in a so far unexplored regime bridging ultracold neutral plasma and ionized nanoclusters. Here, we report on ultrafast cooling of electrons, trapped on orbital trajectories in the long-range Coulomb potential of the dense ionic core, with a cooling rate of 400 K ps−1. Furthermore, our experimental setup grants direct access to the electron temperature that relaxes from 5250 K to below 10 K in less than 500 ns.
