Probing partonic evolution and hadronization via balance functions and correlations of charmed hadrons

Predictions of charm-correlation functions and, more specifically, balance functions are presented in proton-proton (pp) collisions at <a:math xmlns:a="http://www.w3.org/1998/Math/MathML"> <a:mrow> <a:msqrt> <a:msub> <a:mi>s</a:mi> <a:mtext>NN</a:mtext> </a:msub> </a:msqrt> <a:mo>=</a:mo> <a:mn>13</a:mn> <a:mspace width="0.28em"/> <a:mtext>TeV</a:mtext> </a:mrow> </a:math> based on the 8.3 event generator. Correlations are computed for identical and cross-species charmed hadrons in both minimum bias and high- <c:math xmlns:c="http://www.w3.org/1998/Math/MathML"> <c:mrow> <c:msub> <c:mi>p</c:mi> <c:mi mathvariant="normal">T</c:mi> </c:msub> <c:mspace width="0.28em"/> </c:mrow> </c:math> biased collisions. We study the strength of correlations as a function of the number of balanced flavors and investigate the impact of variations of parameters controlling the Lund string fragmentation on the shape and strength of the correlation functions. The feasibility of measurements of the charm-balance function presented is discussed in the context of the future LHC experiments.
