在sqrt(s)= 13 TeV的pp碰撞中包含B+强子的总截面和微分截面的测量

Measurement of the total and differential inclusive B+ hadron cross sections in pp collisions at sqrt(s) = 13 TeV

CMS Collaboration

摘要:

利用CMS实验收集的对应于积分亮度为49.4皮巴的数据,测量了在质心能量为13 TeV的pp碰撞中,B+强子包容性产生的微分截面随B+横动量pT[B]和快度y[B]的变化.测量使用B+到J/psi K+的专用衰变通道,其中J/psi介子衰变为一对μ子。结果表明,在不确定性的理论计算的合理协议。

英文摘要:

The differential cross sections for inclusive production of B+ hadrons are measured as a function of the B+ transverse momentum pT[B] and rapidity y[B] in pp collisions at a centre-of-mass energy of 13 TeV, using data collected by the CMS experiment that correspond to an integrated luminosity of 49.4 inverse picobarns. The measurement uses the exclusive decay channel B+ to J/psi K+, with J/psi mesons that decay to a pair of muons. The results show a reasonable agreement with theoretical calculations within the uncertainties.
