• Chiral density wave versus pion condensation at finite density and zero temperature 

      Andersen, Jens Oluf (Journal article; Peer reviewed, 2018-04)
      The quark-meson model is often used as a low-energy effective model for QCD to study the chiral transition at finite temperature T, baryon chemical potential μB, and isospin chemical potential μI. We determine the parameters ...
    • Collider phenomenology of a unified leptoquark model 

      Faber, T.; Liu, Y.; Porod, W.; Hudec, M.; Malinsky, M.; Staub, F.; Kolesova, Helena (Peer reviewed; Journal article, 2020-05)
      We demonstrate that in a recently proposed unified leptoquark model based on the gauge group SU(4)C×SU(2)L×U(1) R significant deviations from the Standard Model values of R K and R K ∗ can be accommodated without any need ...
    • Highly occupied gauge theories in 2+1 dimensions: A self-similar attractor 

      Boguslavski, K; Kurkela, Aleksi; Lappi, T; Peuron, J (Peer reviewed; Journal article, 2019-11)
      Motivated by the boost-invariant Glasma state in the initial stages in heavy-ion collisions, we perform classical-statistical simulations of SU(2) gauge theory in 2+1 dimensional space-time both with and without a scalar ...
    • Improved Gauss law model and in-medium heavy quarkonium at finite density and velocity 

      Lafferty, David; Rothkopf, Alexander Karl (Peer reviewed; Journal article, 2020-03)
      We explore the in-medium properties of heavy-quarkonium states at finite baryochemical potential and finite transverse momentum based on a modern complex-valued potential model. Our starting point is a novel, rigorous ...
    • Inhomogeneous chiral condensate in the quark-meson model 

      Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article; Peer reviewed, 2017-07-24)
    • On-shell parameter fixing in the quark-meson model 

      Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article; Peer reviewed, 2017-02)
      The quark-meson model is often used as an effective low-energy model for QCD to study the chiral transition at finite temperature T and baryon chemical potential μB. The parameters in the quark-meson model can be found by ...
    • Pion condensation and phase diagram in the Polyakov-loop quark-meson model 

      Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article; Peer reviewed, 2018-10)
      We use the Polyakov-loop extended two-flavor quark-meson model as a low-energy effective model for QCD to study the phase diagram in the μI–T planewhere μI is the isospin chemical potential. In particular, we focus on the ...
    • Supernova constraints on dark flavored sectors 

      Camalich, Jorge Martin; Terol-Calvo, Jorge; Tolos Rigueiro, Laura; Ziegler, Robert (Peer reviewed; Journal article, 2021-06)
      Proto-neutron stars forming a few seconds after core-collapse supernovae are hot and dense environments where hyperons can be efficiently produced by weak processes. By making use of various state-of-the-art supernova ...
    • Thermalization and dynamical spectral properties in the quark-meson model 

      Shen, Lisa; Berges, Jürgen; Pawlowski, Jan M.; Rothkopf, Alexander Karl (Peer reviewed; Journal article, 2020-07)
      We investigate the nonequilibrium evolution of the quark-meson model using two-particle irreducible effective action techniques. Our numerical simulations, which include the full dynamics of the order parameter of chiral ...
    • Towards the nucleon hadronic tensor from lattice QCD 

      Liang, Jian; Draper, Terrence; Liu, Keh-Fei; Rothkopf, Alexander Karl; Yang, Yi-Bo (Peer reviewed; Journal article, 2020-06)
      We present the first calculation of the hadronic tensor on the lattice for the nucleon. The hadronic tensor can be used to extract structure functions in deep inelastic scatterings and to provide information for neutrino-nucleon ...
