- background This phenomenon was interpreted as a signature of deconfinement, 31 arising from color screening in the QGP [169]. However, interactions with the medium constituents can strongly modify quarkonium yields and survival probabilities. In this context, open-charm mesons play an important role, as their thermal modifications may affect charmonium absorption through scattering with comoving hadrons [170, 171, 172]. Moreover, the heavy-quark potential, which is central for the theoretical description o

A year later, in 2022, the 𝑃 Λ 𝜓𝑠 (4338)resonance was observed in flavor-untagged[𝐵− →𝐽∕𝜓+𝑝+̄ 𝑝]decays [107]. Additional experimental studies on the𝑃𝑐 sector can be found in Refs. [108, 109].
