论文摘要
我们研究了非变化净收入对碰撞系统对平衡功能及其积分的测量的影响。我们表明，标称平衡函数定义产生的积分偏离了统一，因为净付费不变。但是，当在足够广泛的实验接受范围内测量时，统一平衡函数的积分被证明可以适当地融合到统一。我们此外，当在有限的横向动量（$ p _ {\ rm t} $）和快速（$ y $）接受度（例如，大型Hadron Collide coldivistive contriders contriders cormentess carterressions进行测量），探索统一平衡功能积分和研究扭曲的收敛速度和研究扭曲造成的扭曲。我们表明，统一平衡函数的形状和积分可能会因现有实验的速度和横向动量接受度的降低而有很大的偏见。
We investigate the impact of non-vanishing net-charge in collision systems on measurements of balance functions and their integrals. We show that the nominal balance function definition yields integrals that deviate from unity because of the non-vanishing net-charge. However, the integral of unified balance functions is shown to appropriately converge to unity when measured in a sufficiently wide experimental acceptance. We furthermore explore the rate of convergence of unified balance functions integrals and study distortions imparted on the shape of balance functions when measurements are carried out in limited transverse momentum ($p_{\rm T}$) and rapidity ($y$) acceptances, such as those featured by experiments at the Large Hadron Collider or the Relativistic Heavy Ion Collider. We show that the shape and integral of unified balance functions may be strongly biased by reductions in the rapidity and transverse momentum acceptances of existing experiments.
