论文摘要
报道了爱丽丝协作进行的近最近测量的电动玻色子生产。 W-boson的产生是通过玻色子的电子衰变在$ \ sqrt {s} = 13 $ tev的pp碰撞中的中期测量的。它也与相对于电子背靠背发射的强子结合测量。在重合离子碰撞中,在$ \ sqrt {s _ {\ mathrm {nn}} = 8.16 $ tev and pb-pb碰撞$ \ sqrt {衰减频道。 PP碰撞中的测量结果揭示了多个Parton相互作用和颜色重新连接机制。在重离子碰撞中,电动玻色子的测量值允许探测碰撞的初始状态。
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.
