Open-flavor heavy hadron production in heavy-ion collisions

We study the production of open-flavor heavy hadrons in relativistic heavy-ion collisions. The hadronization in the quark-gluon plasma is described in the quark coalescence model. We evaluated yields and transverse momentum distributions. A simultaneous study of conventional and exotic hadrons is carried out. The Wigner functions are evaluated using hadron wave functions obtained from a single realistic quark model. Thus, results are presented in a single framework for the production of open-flavor heavy mesons, baryons, and exotic tetraquarks, in particular: <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"> <a:msup> <a:mi>D</a:mi> <a:mn>0</a:mn> </a:msup> </a:math> , <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" display="inline"> <c:msup> <c:mi>B</c:mi> <c:mn>0</c:mn> </c:msup> </c:math> , <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" display="inline"> <e:msub> <e:mi mathvariant="normal">Λ</e:mi> <e:mi>Q</e:mi> </e:msub> </e:math> , <h:math xmlns:h="http://www.w3.org/1998/Math/MathML" display="inline"> <h:msub> <h:mi mathvariant="normal">Σ</h:mi> <h:mi>Q</h:mi> </h:msub> </h:math> , <k:math xmlns:k="http://www.w3.org/1998/Math/MathML" display="inline"> <k:msub> <k:mi mathvariant="normal">Ξ</k:mi> <k:mi>Q</k:mi> </k:msub> </k:math> , <n:math xmlns:n="http://www.w3.org/1998/Math/MathML" display="inline"> <n:msub> <n:mi mathvariant="normal">Ξ</n:mi> <n:mrow> <n:mi>Q</n:mi> <n:msup> <n:mi>Q</n:mi> <n:mo>′</n:mo> </n:msup> </n:mrow> </n:msub> </n:math> , and <q:math xmlns:q="http://www.w3.org/1998/Math/MathML" display="inline"> <q:msub> <q:mi>T</q:mi> <q:mrow> <q:mi>Q</q:mi> <q:msup> <q:mi>Q</q:mi> <q:mo>′</q:mo> </q:msup> </q:mrow> </q:msub> </q:math> ( <s:math xmlns:s="http://www.w3.org/1998/Math/MathML" display="inline"> <s:mi>Q</s:mi> <s:mo>,</s:mo> <s:msup> <s:mi>Q</s:mi> <s:mo>′</s:mo> </s:msup> <s:mo>=</s:mo> <s:mi>c</s:mi> </s:math> or <u:math xmlns:u="http://www.w3.org/1998/Math/MathML" display="inline"> <u:mi>b</u:mi> </u:math> ). The consequences of a partial restoration of chiral symmetry at the hadronization temperature are studied in detail.
