标题： J/Psi dissociation in parity-odd bubbles

摘要： 我们在可能在重离子碰撞中产生的P和CP-odd域（气泡）中计算了夸克胶子的解离率。 在碰撞离子的价夸克产生的磁场存在的情况下，宇称奇异数域会产生电场。 夸克胶子的解离是夸克或反夸克通过该电场中的势垒进行量子隧穿的结果。 夸克胶子共动框架中的电场强度取决于夸克胶子相对于背景磁场的速度。 我们研究了解离率的动量、电场强度和方位角依赖性。 在电磁场中幸存下来的夸克胶子的方位分布具有很强的各向异性；各向异性的形式取决于电场和磁场以及夸克胶子动量之间的关系。 这些特征可以用来探索重离子碰撞中产生的电磁场的性质。 显示英文摘要

摘要： We calculate the quarkonium dissociation rate in the P and CP-odd domains (bubbles) that were possibly created in heavy-ion collisions. In the presence of the magnetic field produced by the valence quarks of colliding ions, parity-odd domains generate electric field. Quarkonium dissociation is the result of quantum tunneling of quark or antiquark through the potential barrier in this electric field. The strength of the electric field in the quarkonium comoving frame depends on the quarkonium velocity with respect to the background magnetic field. We investigate momentum, electric field strength and azimuthal dependence of the dissociation rate. Azimuthal distribution of quarkonia surviving in the electromagnetic field is strongly anisotropic; the form of anisotropy depends on the relation between the electric and magnetic fields and quarkonium momentum. These features can be used to explore the properties of the electromagnetic field created in heavy ion collisions.
