Quark and hybrid stars with renormalization group improvement of NNLO perturbative QCD

Loïc Fernandez, Jean-Loïc Kneur, Marcus Benghi Pinto +3

Recently, the NNLO perturbative QCD pressure of cold and dense symmetric matter, with arbitrary quark masses, has been resummed within the renormalization-group-optimized perturbat…

Susceptibilities and Taylor coefficients of magnetic QCD from perturbation theory

Eduardo S. Fraga, Letícia F. Palhares, Tulio E. Restrepo

We compute the coefficients and of the Taylor expansion for the pressure in powers of in the presence of a large magnetic field within perturbative Q…

Comparing strange and non-strange quark stars within resummed QCD at NLO

Tulio E. Restrepo, Jean-Loïc Kneur, Constança Providência +1

We employ the renormalization group optimized perturbation theory (RGOPT) resummation method to evaluate the equation of state (EoS) for strange () and non-strange ($N_f=2…

Hot and dense pQCD in a very strong magnetic background

Eduardo S. Fraga, Letícia F. Palhares, Tulio E. Restrepo

We compute the pressure, chiral condensate and strange quark number susceptibility from perturbative QCD up to two-loop order at finite temperature and very high magnetic fields wi…

Strongly interacting matter in extreme magnetic fields

Prabal Adhikari, Martin Ammon, Sidney S. Avancini +58

Magnetic fields are ubiquitous across different physical systems of current interest; from the early Universe, compact astrophysical objects and heavy-ion collisions to condensed m…
