用第一批CMS数据测量玻色-爱因斯坦关联
Measurement of Bose-Einstein correlations with first CMS data
摘要：
玻色-爱因斯坦相关性已经使用在0.9和2.36 TeV质心能量下的质子-质子碰撞样本进行了测量，这些样本是由欧洲核子研究中心大型强子对撞机的CMS实验记录的。信号的形式观察到的增强对相同符号的带电粒子与小的相对四动量。的相关粒子发射区域的大小被认为是显着增加与事件的粒子多重性。
英文摘要：
Bose-Einstein correlations have been measured using samples of proton-proton collisions at 0.9 and 2.36 TeV center-of-mass energies, recorded by the CMS experiment at the CERN Large Hadron Collider. The signal is observed in the form of an enhancement of pairs of same-sign charged particles with small relative four-momentum. The size of the correlated particle emission region is seen to increase significantly with the particle multiplicity of the event.
