Vector interaction bounds in NJL-like models from LQCD estimated curvature of the chiral crossover line

Mahammad Sabir Ali, Deeptak Biswas, Chowdhury Aminul Islam

We obtain improved bounds on both the flavor-independent and -dependent vector interactions in a $2+1$-flavor Nambu\textendash Jona-Lasinio (NJL) model using the latest precise LQC…
