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…
Multi-scattering processes and spectral properties of low-energy QCD
Konrad Kockler, Jan M. Pawlowski, Franz R. Sattler +2
We compute quark and meson spectral functions in low-energy QCD, including all-order scatterings and decays of pions and the scalar -mode. For low energies the gluons decouple a…
Pion Distribution Amplitudes from Functional QCD
Lei Chang, Wei-jie Fu, Chuang Huang +2
We present the first functional QCD calculation of the pion distribution amplitude (DA) using the large-momentum effective theory within the functional renormalisation group (fRG)…
Phase structure of strong interaction matter from Functional QCD
Christian S. Fischer, Jan M. Pawlowski
In this contribution to the Encyclopedia of Nuclear Physics, we aim to provide a pedagogical introduction to the functional approach to QCD at finite temperature and chemical poten…
Phase structure and observables at high densities from first principles QCD
Christian S. Fischer, Jan M. Pawlowski
We provide a short review of the progress made in the past decade with functional QCD in the description of the phase structure of QCD. We summarise the most important technical as…
Extracting freeze-out conditions in beam energy scan via functional QCD
Yi Lu, Christian S. Fischer, Fei Gao +2
Fluctuations of conserved charges provide a link between high quality theoretical results and precision measurements of heavy ion collisions. We compare results for ratios of the l…
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…
Electromagnetic properties of heavy-light mesons
A. S. Miramontes, J. Papavassiliou, J. M. Pawlowski
Within the Bethe-Salpeter framework, we present a computation of space-like electromagnetic form factors for pseudoscalar mesons, including light and heavy-light systems. Our appro…
Physics of the gluon mass gap
Mauricio N. Ferreira, Joannis Papavassiliou, Jan M. Pawlowski +1
It has long been known that the gluon propagator in Landau-gauge QCD exhibits a mass gap; and its emergence has been ascribed to the action of the Schwinger mechanism in the gauge…
Critical scaling for spectral functions
Konrad Kockler, Jan M. Pawlowski, Jonas Wessely
We study real-time scalar -theory in 2+1 dimensions near criticality. Specifically, we compute the single-particle spectral function and that of the -channel four-point fun…
Finite density signatures of confining and chiral dynamics in QCD thermodynamics and fluctuations of conserved charges
Yi Lu, Fei Gao, Yu-xin Liu +1
We evaluate thermodynamic observables such as pressure, baryon number, entropy and energy density, as well as the second and fourth order baryon number cumulants in the phase struc…
Juggling with Tensor Bases in Functional Approaches
Jens Braun, Andreas Geißel, Jan M. Pawlowski +2
Systematic expansion schemes in functional approaches require the inclusion of higher order vertices. These vertices are expanded in independent tensor bases with a rapidly increas…
Four-quark scatterings in QCD III
Wei-jie Fu, Chuang Huang, Jan M. Pawlowski +2
We study the full infrared dynamics of 2+1 flavour QCD with the functional renormalisation group approach. We resolve self-consistently the glue dynamics as well as the dynamics of…
Phase structure of quark matter and in-medium properties of mesons from Callan-Symanzik flows
Sebastian Töpfel, Jan M. Pawlowski, Jens Braun
We compute meson spectral functions at finite temperature and density in the quark-meson model, supplemented with a computation of the phase diagram. In particular, we provide a de…
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…
DiFfRG: A Discretisation Framework for functional Renormalisation Group flows
Franz R. Sattler, Jan M. Pawlowski
We introduce DiFfRG (Discretisation Framework for functional Renormalisation Group flows), a comprehensive computational C++ framework for solving functional Renormalisation Group…
Super-Resolving Normalising Flows for Lattice Field Theories
Marc Bauer, Renzo Kapust, Jan M. Pawlowski +1
We propose a renormalisation group inspired normalising flow that combines benefits from traditional Markov chain Monte Carlo methods and standard normalising flows to sample latti…
The causal structure of the quark propagator
Jan M. Pawlowski, Jonas Wessely
We study the causal structure of the quark propagator with the spectral DSE. The spectral gap equation is solved with the input of the spectral representation of the gluon and a ca…
