Glueballs and fractional anomalous determinants at nonzero , and the decays of the X(2370)
Francesco Giacosa, Shahriyar Jafarzade, Győző Kovács +3
Using fractional anomalous determinants, we construct a model of the trace and axial anomalies of a gauge theory at nonzero angle through the couplings to scalar and ps…
Dissecting the moat regime at low energies II: Correlations
Fabian Rennecke, Shi Yin
We study the effects of the moat regime on meson and quark correlation functions and the quark-antiquark potential in low-energy QCD, building on the two-flavor quark meson model i…
Hadronic rescattering effects on net-proton cumulants from functional renormalization group calculations
Qianru Lin, Shi Yin, Jianing Li +4
Net-proton cumulants in the Beam Energy Scan region of heavy-ion collisions are widely used to probe critical fluctuations associated with the conjectured critical endpoint of Quan…
Scalar diquarks in the QCD vacuum
Hosein Gholami, Ugo Mire, Fabian Rennecke +2
While QCD fundamentally only depends on the values of the strong coupling and the quark masses, it exhibits a rich nonperturbative structure at low energies, where composite fields…
Strangeness neutrality and the QCD phase diagram
Wei-jie Fu, Chuang Huang, Jan M. Pawlowski +3
We map out the phase structure of flavour QCD at strangeness neutrality with functional QCD. We find a critical end point at $(T_{\rm CEP},μ_{B,{\rm CEP}})|_{n_S=0} = (92…
Chiral anomaly: from vacuum to Columbia plot
Francesco Giacosa, Győző Kovács, Péter Kovács +2
We use a low-energy effective approach, the extended linear sigma model, to study realizations of the anomaly with different operators, linear and quadratic in the 't Hoof…
Inhomogeneous instabilities in high-density QCD
Jan M. Pawlowski, Fabian Rennecke, Franz R. Sattler
QCD at large densities exhibits a moat regime in the scalar-pseudoscalar sector. The resolution of its dynamics is pivotal for the access to the onset of new phases including the p…
Dissecting the moat regime at low energies I: Renormalization and the phase structure
Fabian Rennecke, Shi Yin
Dense QCD matter can feature a moat regime, where the static energy of mesons is minimal at nonzero momentum. Valuable insights into this regime can be gained using low-energy mode…
QCD phase structure & equation of state: A functional perspective
Fabian Rennecke
The phase structure of QCD remains an open fundamental problem of standard model physics. In particular at finite density, our knowledge is limited. Yet, numerous model studies poi…
The QCD moat regime and its real-time properties
Wei-jie Fu, Jan M. Pawlowski, Robert D. Pisarski +3
Dense QCD matter may exhibit crystalline phases. Their existence is reflected in a moat regime, where mesonic correlations feature spatial modulations. We study the realtime proper…
Dilepton production from moaton quasiparticles
Zohar Nussinov, Michael C. Ogilvie, Laurin Pannullo +4
The phase diagram of QCD may contain a moat regime in a large region of temperature and chemical potential . A moat regime is characterized by quasiparticle moatons (pi…
Anomalous couplings and the Columbia plot
Francesco Giacosa, Győző Kovács, Péter Kovács +2
When the quark masses are lighter than those in QCD, the standard lore is that a chiral transition of first order must emerge for three, light flavors. Recently, however, numerical…
The chiral phase transition and the axial anomaly
Robert D. Pisarski, Fabian Rennecke
To date numerical simulations of lattice QCD have not found a chiral phase transition of first order which is expected to occur for sufficiently light pions. We show how the restor…
Soft modes in hot QCD matter
Jens Braun, Yong-rui Chen, Wei-jie Fu +9
The chiral crossover of QCD at finite temperature and vanishing baryon density turns into a second order phase transition if lighter than physical quark masses are considered. If t…
Medium induced mixing, spatial modulations and critical modes in QCD
Maximilian Haensch, Fabian Rennecke, Lorenz von Smekal
The mixing between the chiral condensate and the density in hot and dense QCD matter is familiar. We show that the mixing relevant for the ground state is considerably more extensi…
Ripples of the QCD Critical Point
Wei-jie Fu, Xiaofeng Luo, Jan M. Pawlowski +2
We investigate the impact of a critical end point (CEP) on the experimentally accessible baryon number fluctuations of different orders. By now, its potential location has been con…
Particle Interferometry in a Moat Regime
Fabian Rennecke, Robert D. Pisarski, Dirk H. Rischke
Dense strongly interacting matter can exhibit regimes with spatial modulations, akin to crystalline phases. In this case particles can have a moat spectrum with minimal energy at n…
Long Range Plan: Dense matter theory for heavy-ion collisions and neutron stars
Alessandro Lovato, Travis Dore, Robert D. Pisarski +61
Since the release of the 2015 Long Range Plan in Nuclear Physics, major events have occurred that reshaped our understanding of quantum chromodynamics (QCD) and nuclear matter at l…
Universal location of Yang-Lee edge singularity in classic O(N) universality classes
Gregory Johnson, Fabian Rennecke, Vladimir V. Skokov
Employing the functional renormalization group approach at next-to-leading order of the derivative expansion, we refine our earlier findings for the location of the Yang-Lee edge s…
Renormalised spectral flows
Jens Braun, Yong-rui Chen, Wei-jie Fu +11
We derive renormalised finite functional flow equations for quantum field theories in real and imaginary time that incorporate scale transformations of the renormalisation conditio…
Universal location of Yang-Lee edge singularity for a one-component field theory in
Fabian Rennecke, Vladimir V. Skokov
We determine the universal location of the Yang-Lee edge singularity in the entire relevant domain of spatial dimensions for the Ising universality class. To that en…
Moat Regimes in QCD and their Signatures in Heavy-Ion Collisions
Fabian Rennecke, Robert D. Pisarski
Dense QCD matter can exhibit spatially modulated regimes. They can be characterized by particles with a moat spectrum, where the minimum of the energy is over a sphere at nonzero m…
Analytical structure of the equation of state at finite density: Resummation versus expansion in a low energy model
Swagato Mukherjee, Fabian Rennecke, Vladimir V. Skokov
For theories plagued with a sign problem at finite density, a Taylor expansion in the chemical potential is frequently used for lattice gauge theory based computations of the equat…
