Volume dependence of baryon number cumulants and their ratios

Gabor A. Almasi, Robert D. Pisarski, Vladimir V. Skokov

We explore the influence of finite volume effects on baryon number fluctuations in a non-perturbative chiral model. In order to account for soft modes, we use the functional renorm…

QCD-inspired determination of NJL model parameters

Paul Springer, Jens Braun, Stefan Rechenberger +1

The QCD phase diagram at finite temperature and density has attracted considerable interest over many decades now, not least because of its relevance for a better understanding of…

In-Medium Spectral Functions of Vector- and Axial-Vector Mesons from the Functional Renormalization Group

Christopher Jung, Fabian Rennecke, Ralf-Arno Tripolt +2

In this work we present first results on vector and axial-vector meson spectral functions as obtained by applying the non-perturbative functional renormalization group approach to…

On the pi pi continuum in the nucleon form factors and the proton radius puzzle

M. Hoferichter, B. Kubis, J. Ruiz de Elvira +2

We present an improved determination of the continuum contribution to the isovector spectral functions of the nucleon electromagnetic form factors. Our analysis includes the m…

Matter Neutrino Resonance Transitions above a Neutron Star Merger Remnant

Yong-Lin Zhu, Albino Perego, Gail C. McLaughlin

The Matter-Neutrino Resonance (MNR) phenomenon has the potential to significantly alter the flavor content of neutrinos emitted from compact object mergers. We present the first ca…

Short Range Correlations and the EMC Effect in Effective Field Theory

Jiunn-Wei Chen, William Detmold, Joel E. Lynn +1

We show that the empirical linear relation between the magnitude of the EMC effect in deep inelastic scattering on nuclei and the short range correlation scaling factor extra…

Consistent parameter fixing in the quark-meson model with vacuum fluctuations

Stefano Carignano, Michael Buballa, Wael Elkamhawy

We revisit the renormalization prescription for the quark-meson model in an extended mean-field approximation, where vacuum quark fluctuations are included. At a given cutoff scale…

Analysis strategies for general spin-independent WIMP-nucleus scattering

Martin Hoferichter, Philipp Klos, Javier Menéndez +1

We propose a formalism for the analysis of direct-detection dark-matter searches that covers all coherent responses for scalar and vector interactions and incorporates QCD constrai…

Scaling violation and the magnetic equation of state in chiral models

Gabor Andras Almasi, Wojciech Tarnowski, Bengt Friman +1

The scaling behavior of the order parameter at the chiral phase transition, the so-called magnetic equation of state, of strongly interacting matter is studied within effective mod…

Polarization and dilepton anisotropy in pion-nucleon collisions

Enrico Speranza, Miklós Zétényi, Bengt Friman

Hadronic polarization and the related anisotropy of the dilepton angular distribution are studied for the reaction . We employ consistent effective interac…

Intercommutation of U(1) global cosmic strings

Guy D. Moore

Global strings (those which couple to Goldstone modes) may play a role in cosmology. In particular, if the QCD axion exists, axionic strings may control the efficiency of axionic d…

Confronting fluctuations of conserved charges in central nuclear collisions at the LHC with predictions from Lattice QCD

P. Braun-Munzinger, A. Kalweit, K. Redlich +1

We construct net baryon number and strangeness susceptibilities as well as correlations between electric charge, strangeness and baryon number from experimental data on the particl…

Color-superconductivity and inhomogeneous chiral symmetry breaking in isospin-asymmetric quark matter

Daniel Nowakowski, Stefano Carignano

We investigate the effects of isospin asymmetry on the competition between color-superconductivity and inhomogeneous chiral symmetry breaking in dense two-flavor quark matter using…

Axion String Dynamics I: 2+1D

Leesa M. Fleury, Guy D. Moore

If the axion exists and if the initial axion field value is uncorrelated at causally disconnected points, then it should be possible to predict the efficiency of cosmological axion…

Superheavy Light Quarks and the Strong P, T Problem

Frank Wilczek, Guy Moore

New superstrong forces, analogous to QCD but featuring a larger mass scale, should they exist, would offer new possibilities for addressing the strong P, T, problem. One can implem…
