Abstract: Abstract. We present results for screening masses of mesons built from light and strange quarks in the temperature range of approximately between 140 MeV to 800 MeV. The lattice computations were performed with 2 + 1 dynamical light and strange flavors of improved (p4) staggered fermions along a line of constant physics defined by a pion mass of about 220 MeV and a kaon mass of 500 MeV. The lattices had temporal extents Nτ = 4, 6 and 8 and aspect ratios of Ns/Nτ ≥ 4. At least up to a temperature of 140 MeV the… Show more

“…Actually, recent experimental data are able to measure and compare charged and pion distributions very accurately [11,12], showing that their difference is negligible within errors at very low p T , where our approach would be applicable. Besides, there are finite temperature lattice analysis measuring pion screening masses [13] which should not differ much from the pole masses analyzed here below but not close to the transition. EM interactions are customarily not included in lattice simulations and therefore an study of their effect in different thermal quantities is interesting in order to support or not such approximation.…”
