The polarisation of prompt [Formula: see text] mesons is measured by performing an angular analysis of [Formula: see text] decays using proton-proton collision data, corresponding to an integrated luminosity of 1.0[Formula: see text], collected by the LHCb detector at a centre-of-mass energy of 7 TeV. The polarisation is measured in bins of transverse momentum [Formula: see text] and rapidity [Formula: see text] in the kinematic region [Formula: see text] and [Formula: see text], and is compared to theoretical models. No significant polarisation is observed.
通过使用质子 - 质子碰撞数据对[公式：见原文]衰变进行角分析，来测量瞬发[公式：见原文]介子的极化，该数据对应于大型强子对撞机底夸克探测器（LHCb）在质心能量为7 TeV时收集的1.0[公式：见原文]的积分亮度。在运动学区域[公式：见原文]和[公式：见原文]中，以横向动量[公式：见原文]和快度[公式：见原文]的区间来测量极化，并与理论模型进行比较。未观察到显著的极化。
