    Resummed lattice QCD equation of state at finite baryon density: strangeness neutrality and beyond

    Szabolcs Borsanyi🇩🇪 · Zoltan Fodor🇩🇪 · Jana N. Guenther🇩🇪 · Ruben Kara🇺🇸 · Paolo Parotto🇺🇸 · Attila Pasztor🇭🇺 · Claudia Ratti🇺🇸 · Kalman K. Szabo🇩🇪

    We calculate a resummed equation of state with lattice QCD simulations at imaginary chemical potentials. This work presents a generalization of the scheme introduced in 2102.06660 to the case of non-zero , focusing on the line of strangeness neutrality. We present results up to on the strangeness neutral line in the temperature range . We also extrapolate the finite baryon density equation of state to small non-zero values of the strangeness-to-baryon ratio . We perform a continuum extrapolation using lattice simulations of the 4stout-improved staggered action with 8, 10, 12 and 16 timeslices.

    Longitudinal dynamics for mesons on the light cone

    Yang Li🇨🇳 · James P. Vary🇺🇸

    We survey a set of proposed light-front models for confinement in the valence quark sector of the mesons and portray similarities as well as differences. We present the spectroscopies for the light mesons that result from a selection of longitudinal confinement forms. We note that the Sturm-Liouville theory provides a unifying framework for many elements of this comparison.
