Electroweak-boson production from small to large collision systems with ALICE at the LHC

Giullaume Taillepied

摘要:

最近的测量电弱玻色子生产进行的ALICE合作的报告。在$\sqrt{s} = 13$ TeV的pp碰撞中,通过玻色子的电子衰变测量了中快度下W玻色子的产生。在重离子碰撞中,在$\sqrt{s_{\mathrm{NN}}} = 8.16$ TeV的p-Pb碰撞和$\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV的Pb-Pb碰撞中,在μ子衰变通道中,测量了W-和Z-玻色子的产生。pp碰撞中的测量揭示了多部分子相互作用和色重联机制。在重离子碰撞中,电弱玻色子的测量可以探测碰撞的初始状态。

英文摘要:

Recent measurements of the electroweak-boson production performed by the ALICE Collaboration are reported. The W-boson production was measured at midrapidity in pp collisions at $\sqrt{s} = 13$ TeV, via the electronic decay of the boson. It was also measured in association with a hadron emitted back-to-back with respect to the electron. In heavy-ion collisions, the W- and Z-boson production was measured at forward rapidity in p--Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 8.16$ TeV and Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV, in their muonic decay channel. Measurements in pp collisions shed light on multiple parton interactions and colour reconnection mechanisms. In heavy-ion collisions the measurements of electroweak bosons allow to probe the initial state of the collision.
