Effects of kinematic cuts on net-electric charge fluctuations

Understand

The effects of kinematic cuts on electric charge fluctuations in a gas of charged particles are discussed.

• We consider a very transparent example of an ideal pion gas with quantum statistics, which can be viewed as a multi-component gas of Boltzmann particles with different charges and masses.
• Cumulants of net-electric charge fluctuations $\chi_n^Q$ are calculated in a static and expanding medium with flow parameters adjusted to the experimental data.
• We show that the transverse momentum cut, $p_{t_\text{min}}\leq p_t\leq p_{t_\text{max}}$, weakens the effects of Bose statistics, i.e.
