Mott dissociation of pions and kaons in hot, dense quark matter

Abstract: We describe the Mott dissociation of pions and kaons within a Beth-Uhlenbeck approach based on the PNJL model, which allows for a unified description of bound, resonant and scattering states. Within this model we evaluate the temperature and chemical potential dependent modification of the phase shifts both in the pseudoscalar and scalar isovector meson channels for $N_f=2+1$ quark flavors. We show that the character change of the pseudoscalar bound states to resonances in the continuum at the Mott transition … Show more

“…9, we have shown the variation of m π as a function of temperature at two different values of an external magnetic field. At lower values of temperature, the mass of pions are almost independent of T. At some particular temperature, m π suffers a sudden jump (discontinuity) corresponding to Mott transition [41,42,[53][54][55]. The jump structure is in qualitative agreement with most of the studies.…”

“…The problem is how to relate the model points with the experimental ones. Here we use the idea to map points with a fixed value of µ/T on the line in phase diagram of our PNJL model to points on the curve fitted to statistical model analyses [21]. Let us take this scan line as a critical line in PNJL model, see the left panel of Fig.…”

“…When the meson mass exceeds the total value of its consistent P 0 > m i + m j , the meson turns into the resonance state. In this case, the complex properties of the integrals have to be taken into account and the solution has to be defined in the form (12) splits into two equations from which the meson mass M M and the meson width M can be obtained [30].…”
