Nuclear matter at high density: Phase transitions, multiquark states, and supernova outbursts

Abstract: Phase transition from hadronic matter to quark-gluon matter is discussed for various regimes of temperature and baryon number density. For small and medium densities, the phase transition is accurately described in the framework of the Field Correlation Method, whereas at high density predictions are less certain and leave room for the phenomenological models. We study formation of multiquark states (MQS) at zero temperature and high density. Relevant MQS components of the nuclear matter can be described using… Show more

“…This concerns first of all the fragmentation functions (4) and (5), which were justified in the quark-gluon string model only in the boundary regions near x=0, x=2 and x=3. The calculation of fragmentation functions in the whole x range is still unsolved problem of the model and the fragmentation functions (4,5) are the simplest possible (and widely used) functions, satisfying above mentioned boundary conditions. Moreover, in Fig.…”

“…If dibaryons exist and if they even survive in a nuclear surrounding, then they should have an impact on the nuclear equation of state [49][50][51], which is of relevance not only for heavy-ion collisions but also for very compact stellar objects like neutron stars.…”
