pp碰撞中重味介子衰变轻子的热化

On the thermalisation of leptons from heavy-flavour meson decay in pp collisions

Rahul Ramachandran Nair

摘要:

结果表明,在用PYTHIA 8事件发生器模拟的$\sqrt{s} = 13$ TeV质子-质子碰撞中,重味介子衰变产生的$μ^{\pm}$可以根据其光阵面变量的值分成两组,使得这两组中的一组$μ^{\pm}$遵循玻尔兹曼统计,具有近似各向同性的角分布.对于$e^{\pm}$,在这些碰撞中,从重味介子的衰变中没有观察到类似的效应。

英文摘要:

It is shown that the $μ^{\pm}$ originating from the decay of heavy-flavour mesons in the simulated proton-proton collisions at $\sqrt{s} = 13$ TeV using the PYTHIA 8 event generator can be made into two groups based on the value of their light front variable such that one among these two groups of $μ^{\pm}$ follow the Boltzmann statistics with a nearly isotropic angular distribution. A similar effect is not observed for $e^{\pm}$ from the decay of heavy-flavour mesons in these collisions.
