Chiralspin symmetry and confinement Open
Interesting lattice QCD simulations at high temperature in QCD and particular truncated studies have shown the emergence of an unexpected group symmetry, so called chiralspin. However this is not a symmetry of the QCD action for free quark…

On SU(2)CS-like groups and invariance of the fermionic action in QCD Open
In this work, we introduce some new U(1) symmetry groups of the free fermionic action in Euclidean space–time, which are a consequence of parity and time-reversal symmetries. Afterwards, we discuss how the introduction of a gauge interacti…

In these proceedings we present preliminary results for the masses of the proton, neutron and Ω− baryons obtained from QCD+QED lattice simulations performed with four dynamical quarks using C∗ boundary conditions. These results are part of…

An update on QCD+QED simulations with C* boundary conditions Open
We present two novelties in our analysis of fully dynamical QCD+QED ensembles with C* boundary conditions. The first one is the explicit computation of the sign of the Pfaffian. We present an algorithm that provides a significant speedup c…

First results on QCD+QED with C$^{*}$ boundary conditions Open
Accounting for isospin-breaking corrections is critical for achieving subpercent precision in lattice computations of hadronic observables. A way to include QED and strong-isospin-breaking corrections in lattice QCD calculations is to impo…

Gap in the Dirac spectrum and quark propagator symmetries in lattice QCD Open
Recent studies on lattice QCD have shown the emergence of large symmetries at high temperature. This includes not only the restoration $SU(n_F)_L \times SU(n_F)_R$, but also the effective emergence of an unexpected symmetry group, namely $…

From String Breaking to Quarkonium Spectrum Open
We present a preliminary computation of potentials between two static quarks in $n_f=2$ QCD with O(a) improved Wilson fermions. We explore different smearing choices (HYP, HYP2 and APE) and their effect on the signal to noise ratio in the …

Chiral-spin symmetry emergence in baryons and eigenmodes of the Dirac operator Open
Truncating the low-lying modes of the lattice Dirac operator results in an emergence of the chiral-spin symmetry $SU(2)_{CS}$ and its flavor extension $SU(2N_F)$ in hadrons. These are symmetries of the quark - chromo-electric interaction a…

The chirally symmetric baryon parity-doublet model can be used as an\neffective description of the baryon-like objects in the chirally symmetric\nphase of QCD. Recently it has been found that above the critical temperature\nhigher chiralsp…

Distribution of the Dirac modes in QCD Open
It was established that distribution of the near-zero modes of the Dirac operator is consistent with the Chiral Random Matrix Theory ( CRMT ) and can be considered as a consequence of spontaneous breaking of chiral symmetry ( SBCS ) in QCD…
