Charmed baryon spectrum from lattice QCD near the physical point

Spectrum of the ground state and excited states of charmed baryons was evaluated in the lattice QCD, the first principle of hadronic interaction. We deliver the spectrum of the positive and negative parity baryons with one, two or three charmed quarks. A variational approach was employed by the use of multiple operators with different Dirac matrix configurations and the smearings.

Based on my recent research, I will present results on numerical simulations of pA reactions (p: proton, A: nucleus). I will specially explain in detail the experimentally measurable di-lepton spectrum that results from this sort of reaction. Furthermore, I will discuss what kind of $$phi$$ meson spectral function best reproduces the experimental results obtained so far.

The $$phi$$ meson with finite momentum in a dense medium

Kim, H.-J.*; Gubler, P.

Physics Letters B, 805, p.135412_1 - 135412_8, 2020/06

The dispersion relation of the $$phi$$ meson in nuclear matter is studied in a QCD sum rule approach. In a dense medium, longitudinal and transverse modes of vector particles can have independently modified dispersion relations due to broken Lorentz invariance. Employing the full set of independent operators and corresponding Wilson coefficients up to operator dimension-6, the $$phi$$ meson QCD sum rules are analyzed with changing densities and momenta. The non-trivial momentum dependence of the $$phi$$ meson mass is found to have opposite signs for the longitudinal and transverse modes. Specifically, the mass is reduced by 5 MeV for the longitudinal mode, while its increase amounts to 7 MeV for the transverse mode, both at a momentum scale of 1 GeV. In an experiment which does not distinguish between longitudinal and transverse polarizations, this could in principle be seen as two separated peaks at large momenta.

Exact vector channel sum rules at finite temperature

Gubler, P.; Sato, Daisuke*

JPS Conference Proceedings (Internet), 26, p.024023_1 - 024023_5, 2019/11

In this talk, I will introduce and review several exact sum rules of the vector channel spectral function at finite temperature, which we have derived in a recent paper. I will also discuss an explicit check of these sum rules in perturbation theory and possible application to the analysis of lattice QCD data.
