Charm Exotics: Parallel 1
- Christina Markert (University of Texas at Austin (US))
In recent years, a significant theoretical effort has been made towards a dynamical description of quarkonia inside the Quark-Gluon Plasma (QGP), using the open quantum systems formalism. In this framework, one can get a real-time description of a quantum system (here the quarkonium) in interaction with a thermal bath (the QGP) by integrating out the bath degrees of freedom and studying the...
Heavy quarks (HQs) are mostly created in the very initial stages of the relativistic heavy-ion collisions and are identified as effective probes to study the properties of the quark-gluon plasma (QGP). It is believed that an intense magnetic field has been created in the early stages of non-central collisions. The interactions of the heavy quarks with the magnetized medium particles are...
The first evidence for X(3872) production in relativistic heavy ion collisions is reported. The X(3872) hadron is studied in PbPb collisions at a center-of-mass energy of 5.02 TeV per nucleon pair, using the decay chain $X(3872)\rightarrow J/\psi\pi\pi\rightarrow \mu^{+}\mu^{-}\pi^{+}\pi^{-}$ decay chain. The data were recorded with the CMS detector in 2018 and correspond to an integrated...
Exploring the nature of exotic multiquark candidates such as the X(3872) plays a pivotal role in understanding quantum chromodynamics (QCD). Despite significant efforts, consensus on their internal structures is still lacking. As a prime example, it remains a pressing open question to decipher the X(3872) state between two popular exotic configurations: a loose hadronic molecule or a compact...
In relativistic nuclear collisions the production of hadrons with light (u,d,s) quarks is quantitatively described in the framework of the Statistical Hadronization Model (SHM). Since charm quarks are dominantly produced in initial hard collisions but interact strongly in the hot fireball, charmed hadrons can be incorporated into the SHM by treating charm quarks as 'impurities' with thermal...
