Functional renormalization group study of the quark-meson model with $$\omega $$ ω and $$\rho $$ ρ vector mesons

open access: yesEuropean Physical Journal C: Particles and Fields
We employ the functional renormalization group flow equations to investigate the phase structure of the two-flavor quark-meson model in the presence of a finite isospin chemical potential, incorporating interactions with omega and rho vector mesons.

Isospin strikes back

open access: yesEuropean Physical Journal C: Particles and Fields
Assuming isospin conservation, the decay of a $$c\bar{c}$$ c c ¯ vector meson into the $$\Lambda \bar{\Sigma }^0+\mathrm{c.c.}$$ Λ Σ ¯ 0 + c . c . final state is purely electromagnetic.
