摘要
ALICE合作组在LHC上测量了质心能量sqrt(s)=2.76 TeV的pp碰撞中J/ψ的包容产生。本文给出的结果涉及快度范围|y|<0.9和2.5<y<4，分别通过测量电子对和缪子对衰变道获得。两个道的积分亮度分别为L^e_int=1.1 nb^-1和L^mu_int=19.9 nb^-1，相应的信号统计量为N_J/psi^e+e-=59 +/- 14和N_J/psi^mu+mu-=1364 +/- 53。我们给出了所研究的两个快度区域的dsigma_J/psi/dy，以及前向快度范围内横动量区间0<p_t<8 GeV/c的d^2sigma_J/psi/dydp_t。结果与先前在sqrt(s)=7 TeV下发表的结果以及理论计算进行了比较。
