论文摘要
广泛的观念是,在Quark-Gluon-plasma中淬火(QGP)在Parton风味组成中与真空中的喷气机相似。我们证明,虽然真空飞机的柔软至半硬化(低至中间的横向动量($ p_t $)]扇形主要是玻色杆人,即由gluons组成,\ emph {足够充分}的喷气喷气机可以具有中间动量部门,其中间动量部门主要由ferminiminiminiminionfermininiend fyerminiencienciencions,and公平,并且是偏见的公平。我们使用领先的扰动QCD工艺证明,从gluon越过QGP作为喷气机的一部分到夸克或反quark的风味转换率,而不是反向过程,随着$ p_t $的下降而稳步增长。简单的图表估计值之后是静态介质中的各种现实模拟。在完全逼真的模拟中研究了这种风味的增加与中间$ p_t $处观察到的巴属增强的关系。
The widespread notion that jets quenched in a Quark-Gluon-Plasma (QGP) are similar in their parton flavor composition to jets in vacuum is critically examined. We demonstrate that while the soft to semi-hard [low to intermediate transverse momentum ($p_T$)] sector of vacuum jets are predominantly bosonic i.e., composed of gluons, \emph{sufficiently} quenched jets can have an intermediate momentum sector that is predominantly fermionic, dominated by quarks and antiquarks. We demonstrate, using leading order perturbative QCD processes, that the rate of flavor conversion from a gluon traversing the QGP as part of a jet, to a quark or antiquark, versus the reverse process, grows steadily with falling $p_T$. Simple diagrammatic estimates are followed by a variety of realistic simulations in static media. The relation of this increase in flavor to the observed baryon enhancement at intermediate $p_T$ is studied in a fully realistic simulation.
