Phenomenological QCD equations of state for neutron stars

Toru Kojo, Philip D. Powell, Yifan Song +1

We delineate the properties of QCD matter at baryon density n_B=1-10n_0 (n_0: nuclear saturation density), through the construction of neutron star equations of state that satisfy…

A non-boost-invariant solution of relativistic hydrodynamics in 1+3 dimensions

Yoshitaka Hatta, Bo-Wen Xiao, Di-Lun Yang

We present a new solution of relativistic hydrodynamics in 1+3 dimensions which depends on both the transverse coordinate and rapidity. At early times the flow expands dominantly l…

Anisotropic Inflation with General Potentials

Jiaming Shi, Xiaotian Huang, Taotao Qiu

Anomalies in recent observational data indicate that there might be some "anisotropic hair" generated in an inflation period. To obtain general information about the effects of thi…

Two-loop current-current operator contribution to the non-leptonic QCD penguin amplitude

Guido Bell, Martin Beneke, Tobias Huber +1

The computation of direct CP asymmetries in charmless B decays at next-to-next-to-leading order (NNLO) in QCD is of interest to ascertain the short-distance contribution. Here we c…

Chiral electric field in relativistic heavy-ion collisions at energies available at the BNL Relativistic Heavy Ion Collider and at the CERN Large Hadron Collider

Yang Zhong, Chun-Bin Yang, Xu Cai +1

It was proposed that the electric fields may lead to chiral separation in QGP, which is called the chiral electric separation effect. The strong electromagnetic field and the QCD v…
