$\sqrt{s}=900$ GeV pp碰撞中的两π玻色-爱因斯坦关联

Two-pion Bose-Einstein correlations in pp collisions at $\sqrt{s}=900$ GeV

ALICE Collaboration

摘要:

本文报道了在大型强子对撞机上进行的ALICE实验对$\sqrt{s}=900$ GeV的pp碰撞中两π介子关联函数的测量。我们的分析表明,HBT半径的增加,增加事件的多重性,在粒子和核碰撞中进行的其他测量。相反,在RHIC和Tevatron上观察到的半径随横向动量增加而强烈减小的现象,在我们的数据中并不明显。

英文摘要:

We report on the measurement of two-pion correlation functions from pp collisions at $\sqrt{s}=900$ GeV performed by the ALICE experiment at the Large Hadron Collider. Our analysis shows an increase of the HBT radius with increasing event multiplicity, in line with other measurements done in particle- and nuclear collisions. Conversely, the strong decrease of the radius with increasing transverse momentum, as observed at RHIC and at Tevatron, is not manifest in our data.
