| Summary: | Analysis of the (i) charge balance function and (ii) fluctuations of the net electric charge of hadrons in <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>P</mi><mi>b</mi></mrow></semantics></math></inline-formula>+<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>P</mi><mi>b</mi></mrow></semantics></math></inline-formula> collisions at center-of-mass energy 2.76 TeV per nucleon pair was performed within a two-component <span style="font-variant: small-caps;">hydjet++</span> model. It is shown that neither the widths of the balance function nor the strongly intensive quantities, <i>D</i> and Σ, used to describe the net-charge fluctuations, can be reproduced within the model based on a grand canonical ensemble approach for generating multiparticle production. To solve this problem, it is necessary to take into account exact charge conservation in an event-by-event basis. The corresponding procedure was developed and implemented in the modified <span style="font-variant: small-caps;">hydjet++</span> model. It provides a fair description of the experimental data. |
