Light Quark Spin-Flavor Symmetry for Baryons Containing a Heavy Quark in Large N QCD [PDF]

Phys.Lett.B315:431-437,1993, 1993
The couplings and interactions of baryons containing a heavy quark are related by light quark spin-flavor symmetry in the large $N$ limit. The single pion coupling constant which determines all heavy quark baryon-pion couplings is equal to the pion coupling constant for light quark baryons.

Spin polarization induced by the hydrodynamic gradients

Journal of High Energy Physics, 2021
We systematically analyze the effects of the derivatives of the hydrodynamic fields on axial Wigner function that describes the spin polarization vector in phase space.

Quark Number Susceptibility with Finite Quark Mass in Holographic QCD [PDF]

Prog. Theor. Phys. 126 (2011), 735-751, 2010
We study the effect of a finite quark mass on the quark number susceptibility in the framework of holographic QCD. We work in a bottom-up model with a deformed AdS black hole and D3/D7 model to calculate the quark number susceptibility at finite temperature with/without a finite quark chemical potential. As expected the finite quark mass suppresses the

A Novel Multi-Gene Detection Platform for the Analysis of miRNA Expression

Scientific Reports, 2018
The study of miRNAs and their roles as non-invasive biomarkers has been intensely conducted in cancer diseases over the past decade. Various platforms, ranging from conventional qPCRs to Next Generation Sequencers (NGS), have been widely used to analyze ...

Quark mass density- and temperature- dependent model for bulk strange quark matter [PDF]

Phys.Rev. C65 (2002) 035202, 2002
It is shown that the quark mass density-dependent model can not be used to explain the process of the quark deconfinement phase transition because the quark confinement is permanent in this model. A quark mass density- and temperature-dependent model in which the quark confinement is impermanent has been suggested.

Probing new physics in class-I B-meson decays into heavy-light final states

Journal of High Energy Physics, 2021
With updated experimental data and improved theoretical calculations, several significant deviations are being observed between the Standard Model predictions and the experimental measurements of the branching ratios of B ¯ s 0 → D s ∗ + L ...

Search for medium response to jet quenching via hadron chemistry around the quenched jets [PDF]

EPJ Web of Conferences
We present a unique signal of medium response to jet quenching: the enhancement of baryon-to-meson ratios for associated particles at intermediate transverse momentum around the triggered quenched jets.

Jet tomography in high-energy nuclear collisions [PDF]

EPJ Web of Conferences, 2019
When an energetic parton traversing the QCD medium, it may suffer multiple scatterings and lose energy. This jet quenching phenomenon may lead to the suppression of leading hadron productions as well as medium modifications of full jet observables in ...

Positive magnetoresistance induced by hydrodynamic fluctuations in chiral media

Journal of High Energy Physics, 2021
We analyze the combined effects of hydrodynamic fluctuations and chiral magnetic effect (CME) for a chiral medium in the presence of a background magnetic field. Based on the recently developed non-equilibrium effective field theory, we show fluctuations
