The structure of exotic resonances that do not trivially fit the usual quark model expectations
has been a matter of intense scientific debate during the last two decades. A possible way of …

Heavy-ion collisions provide a unique opportunity to study the nature of X (3872) compared
with electron-positron and proton-proton (antiproton) collisions. We investigate the centrality …

The dependence of the production of the X (3872) meson on the hadron multiplicity in pp
collisions has been used as evidence against X being a charm-meson molecule. The …

We have determined the production cross sections of the X (3872) state in the reactions D¯
D→ π X, D¯* D→ π X, and D¯* D*→ π X, information which is useful for studies of the X …

The first evidence for X (3872) production in relativistic heavy ion collisions is reported. The
X (3872) production is studied in lead-lead (Pb-Pb) collisions at a center-of-mass energy of s …

The production of the X (3872) X (3872) particle in heavy-ion collisions has been
contemplated as an alternative probe of its internal structure. To investigate this conjecture …

Exploring the nature of exotic multiquark candidates such as the X (3872) plays a pivotal
role in understanding quantum chromodynamics (QCD). Despite significant efforts …

We study the hadronic effects on the X (3872) meson abundance in heavy ion collisions. We
evaluate the absorption cross sections of the X (3872) meson by pions and rho mesons in …

We calculate the time evolution of the X (3872) abundance in the hot hadron gas produced
in the late stage of heavy ion collisions. We use effective field Lagrangians to obtain the …

The new data reported by ALICE on the production of light nuclei with p⊥≲ 10 GeV in Pb-Pb
collisions at s NN= 2.76 TeV are used to compute an order-of-magnitude estimate of the …
