Quarkonia suppression in small systems with a nonadiabatic evolution

In high multiplicity proton-proton (pp) collisions, the formation of a deconfined state of quarks and gluons akin to Heavy Ion Collisions (HIC) has been a subject of significant interest.In protonproton (pp) collisions, the transverse size of the system is comparable to the longitudinal (Lorentz contracted) dimension, unlike the case in Nucleus-Nucleus (A -A) collision, leading to a hitherto unexplored effect of rapid decrease of temperature of the medium on quark-antiquark bound states.This allows us to probe a unique possibility of hadronization occurring before quarkonia dissociation within the medium.In small systems, a rapid change in temperature also introduces sudden changes in the Hamiltonian.This scenario prompts consideration of non-adiabatic evolution, challenging the traditional adiabatic framework.We demonstrate that non-adiabatic evolution may extend the longevity of quark-anti-quark bound states in pp collisions, even at higher multiplicities, offering new insights into the dynamics of strongly interacting matter produced in smaller collision systems.
