Abstract We study the effect of a uniform magnetic field B → $$ \overrightarrow{B} $$ on the decays π − → l − ν ¯ l $$ {\pi}^{-}\to {l}^{-}{\overline{\nu}}_l $$ , where l − = e −, μ −, carrying out a general analysis that includes f

The large Nc limit plays a fundamental role in the study of non-abelian gauge theories such as quantum chromodynamics (QCD). Since its discovery in 1974 by't Hooft, the 1/Nc expansion has provided crucial insights into the non-perturbative aspects of

We review the current status of the research on effective nonlocal NJL-like chiral quark models with separable interactions, focusing on the application of this approach to the description of the properties of hadronic and quark matter under extreme

We calculate the pole masses of pseudoscalar mesons in a strongly magnetized medium within the framework of the SU(3) Nambu-Jona--Lasinio model, using a magnetic field-independent regularization scheme. We employ both a constant and a magnetic field-

We study the behavior of two-flavor dense quark matter under the influence of an external magnetic field in the framework of a nonlocal chiral quark model with separable interactions. The nonlocality is incorporated in the model by using a Gaussian f

We analyze the features of strongly interacting matter in the presence of nonzero isospin chemical potential $\mu_I$, within a nonlocal two-flavor Polyakov-Nambu-Jona-Lasinio (PNJL) model. For a system at finite temperature $T$, we describe the behav

The behavior of charged pion masses in the presence of a static uniform magnetic field is studied in the framework of the two-flavor NJL model, using a magnetic field-independent regularization scheme. Analytical calculations are carried out employin

We study the behavior of neutral meson properties in the presence of a static uniform external magnetic field in the context of nonlocal chiral quark models. The formalism is worked out introducing Ritus transforms of Dirac fields, which allow to obt

The properties of magnetized color superconducting cold dense quark matter under compact star conditions are investigated using an $SU(2{)}_{f}$ Nambu Jona-Lasinio (NJL)-type model in which the divergences are treated using a magnetic field independe
