Functional renormalization of QCD in $1 + 1$ dimensions: four-fermion interactions from quark-gluon dynamics

Eric Oevermann, Adrian Koenigstein, Stefan Floerchinger

Quantum Chromodynamics in two spacetime dimensions is investigated with the Functional Renormalization Group. We use a functional formulation with covariant gauge fixing and derive…

Inhomogeneous condensation in the Gross-Neveu model in noninteger spatial dimensions $1 \leq d < 3$ . II. Nonzero temperature and chemical potential

Adrian Koenigstein, Laurin Pannullo

We continue previous investigations of the (inhomogeneous) phase structure of the Gross-Neveu model in a noninteger number of spatial dimensions ( $1 \leq d < 3$ ) in the limit of an…

Detecting inhomogeneous chiral condensation from the bosonic two-point function in the $(1 + 1)$ -dimensional Gross-Neveu model in the mean-field approximation

Adrian Koenigstein, Laurin Pannullo, Stefan Rechenberger +2

The phase diagram of the $(1 + 1)$ -dimensional Gross-Neveu model is reanalyzed for (non-)zero chemical potential and (non-)zero temperature within the mean-field approximation. By…

Bosonic fluctuations in the $(1 + 1)$ -dimensional Gross-Neveu(-Yukawa) model at varying $μ$ and $T$ and finite $N$

Jonas Stoll, Niklas Zorbach, Adrian Koenigstein +2

Using analogies between flow equations from the Functional Renormalization Group and flow equations from (numerical) fluid dynamics we investigate the effects of bosonic fluctuatio…

Phenomenology of $J^{P C} = 3^{--}$ tensor mesons

Shahriyar Jafarzade, Adrian Koenigstein, Francesco Giacosa

We study the strong and radiative decays of the anti-quark-quark ground state $J^{P C} = 3^{--}$ ( $n^{2 S + 1} L_{J} = 1^{3} D_{3}$ ) nonet { $ρ_{3} (1690)$ , $K_{3}^{*} (1780)$ , $ϕ_{3} (…

How the axial anomaly controls flavor mixing among mesons

Francesco Giacosa, Adrian Koenigstein, Robert D. Pisarski

It is well known that because of the axial anomaly in QCD, mesons with $J^{P} = 0^{-}$ are close to $S U (3)_{V}$ eigenstates: the $e t a^{'} (958)$ meson is largely a singlet,…

Phenomenology of pseudotensor mesons and the pseudotensor glueball

Adrian Koenigstein, Francesco Giacosa

We study the decays of the pseudotensor mesons $[π_{2} (1670), K_{2} (1770), η_{2} (1645), η_{2} (1870)]$ interpreted as the ground-state nonet of $1^{1} D_{2}$ $q ˉ q$ states us…
