   …conservation in a finite volume accounts for this, but when it is imposed on hadrons it leaves the $\phi$ meson unsuppressed, contrary to observation. We impose the conservation law on the strange quarks in a…

   …fermion ensembles. We study correlation functions with nucleon and multihadron nucleon-$\sigma$-meson interpolating operators. The analysis is performed using three gauge ensembles, including one ensemble…

3. Thermal properties of the $\rho$ meson from a machine-learning-improved holographic QCD model hep-ph · 14 Oct · 3 hits

   The thermal properties of the \(\rho\) meson are revisited within the soft-wall AdS/QCD framework. The dilaton background is calibrated against…

   In this work, we study spectral functions of heavy and exotic mesons in a self-consistent Einstein-Maxwell-dilaton model at finite temperature and chemical potential,…

   …that allows us to include both quark and hadron degrees of freedom as well as the full complexity of the meson-exchange potential in a systematic way. For illustration, the formalism to leading order (LO) is…

   …diagnostics of the mean-field functional, rather than a preferred phenomenological kernel. Omitted thermal mesons can change the low-temperature slope test, and the static derivative does not determine a real-time…

   …to construct consistent $ccs$ and $bbs$ parity multiplets and a conditional extension to $bcs$. Under meson-to-baryon parity-gap transfer, the $349$ MeV input from the $D_s$ sector gives negative-parity $ccs$…

   Tests of lepton-flavour universality in semileptonic \(B\)-meson decays provide sensitive probes of physics beyond the Standard Model. The Belle and Belle II…
