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.

Are there compact heavy four-quark bound states? [PDF]
, 2007 We present an exact method to study four-quark systems based on the hyperspherical harmonics formalism. We apply it to several physical systems of interest containing two heavy and two light quarks using different quark-quark potentials.

Light Quark Spin-Flavor Symmetry for Baryons Containing a Heavy Quark in Large N QCD
, 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 ...

Freeze-in Dirac neutrinogenesis: thermal leptonic CP asymmetry
European Physical Journal C: Particles and Fields, 2020 We present a freeze-in realization of the Dirac neutrinogenesis in which the decaying particle that generates the lepton-number asymmetry is in thermal equilibrium.

CP asymmetry in the angular distribution of τ → KS πν τ decays
Journal of High Energy Physics, 2020 In this work, we study the C P asymmetry in the angular distribution of τ → K S πν τ decays, taking into account the known C P violation in K 0 − K ¯ 0 $$ {K}^0-{\overline{K}}^0 $$ mixing. It is pointed out for the first time that, once the well-measured

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 ...

HARD QUARK-QUARK SCATTERING WITH EXCLUSIVE REACTIONS* [PDF]
Le Journal de Physique Colloques, 1985 We present data from π-p → elastic and ρ-p final states for scattering at 90° center of mass, -t = 9 GeV2/c2. A large ρ-p signal is seen and the ρ- are strongly polarized. This polarization tests a QCD prediction that quarks cannot flip helicity. The test fails dramatically.

Performance of pyDock in 8th CAPRI: Energy‐Based Scoring Applied to Docking and AlphaFold Models
Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT The 8th CAPRI edition has shown a significant evolution in the field of protein–protein complex structure prediction. We have participated in all 11 targets proposed in this edition, involving domain‐domain, protein–protein, protein‐peptide, and protein‐DNA interactions, including homo‐ and hetero‐meric interfaces.

Quark Number Susceptibility with Finite Quark Mass in Holographic QCD
, 2011 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 ...
