Nilanjan Chaudhuri, Sourav Duari, Pradip Roy, Sourav Sarkar

AI总结:

本文利用硬热圈近似研究手征不对称夸克-胶子等离子体的热光子发射,发现手征不平衡导致准粒子模式分裂并引入与化学势平方成正比的软贡献附加项,从而增强热光子发射率。

摘要:

我们利用硬热圈近似评估了手征不对称夸克-胶子等离子体的热光子发射率。在有限温度下普遍存在的准粒子和plasmino模式在手征不平衡存在时分裂为L和R模式,并发现它们以不同的方式色散,获得不同的热质量。从推迟自能得到的对热光子发射率的软贡献被发现包含与夸克化学势和手征化学势的平方成正比的附加项,这些项被发现会在手征不平衡存在时增强热光子发射。

英文摘要:

We evaluate the thermal photon emission rate from a chirally asymmetric quark gluon plasma using the Hard Thermal Loop approximation. The quasiparticle and plasmino modes prevalent at finite temperature split into L and R-modes in the presence of chiral imbalance and are found to disperse differently acquiring different thermal masses. The soft contribution to the thermal photon emission rate obtained from the retarded self-energy is found to contain additional terms proportional to the square of the quark and chiral chemical potentials which is found to cause an enhancement to thermal photon emission in the presence of chiral imbalance.
