用ALICE实验测量pp碰撞带电喷流中的强子成分

Measurement of hadron composition in charged jets from pp collisions with the ALICE experiment

摘要:

我们首次测量了强子对撞机喷流中带电π介子、K介子和(反)质子的产生。测量是在大型强子对撞机上使用$2\times10^8$最小偏置pp碰撞的ALICE探测器进行的,质心能量为$\sqrt{s}=7$ TeV。本文给出了5- 20 $\textrm{GeV}/c$的$p_\textrm{T}$带电喷流中的$π$、K和p横动量($p_\textrm{T}$)谱以及约化动量(${z^\textrm{ch}\equiv p_\textrm{T}^\textrm{track}/p_\textrm{T, jet}^\textrm{ch}}$)谱。的测量相比,蒙特卡罗计算。

英文摘要:

We report the first measurement of charged pion, kaon and (anti-)proton production in jets from hadron colliders. The measurement was carried out with the ALICE detector using $2\times10^8$ minimum bias pp collisions at a centre-of-mass energy of $\sqrt{s}=7$ TeV at the LHC. We present the $π$, K and p transverse momentum ($p_\textrm{T}$) spectra, as well as the spectra of the reduced momentum (${z^\textrm{ch}\equiv p_\textrm{T}^\textrm{track}/p_\textrm{T, jet}^\textrm{ch}}$), in charged jets of $p_\textrm{T}$ between 5--20 $\textrm{GeV}/c$. The measurement is compared to Monte Carlo calculations.
