Imposing the SU(3) flavor eigenstate condition on udsc c-bar pentaquarks in a constituent quark model yields two structures matching the masses of P_cs(4338) and P_cs(4459) plus two additional predicted states below the J/ψΛ threshold.
pQCD calculations predict ~90% longitudinal polarization in B_c to J/psi or psi(2S) plus rho or K* mediated light meson pairs, with one branching ratio ratio matching LHCb at 2.67 vs 2.80.
Proposes a manifestly duality- and Lorentz-invariant local action for QED with monopoles derived from Sen's formalism using field strengths as dynamical variables, with consistent tree- and loop-level results.
Branching ratios for hyperon semi-invisible decays (hadronic ~10^{-5}, radiative <10^{-7}) are calculated with sizable one-loop corrections using effective Lagrangians.
SModelS v3.0 largely reproduces ATLAS pMSSM electroweak-ino constraints, with CMS inclusion and combinations tightening limits but leaving some light ino parameter space viable.
Realistic nuclear cluster wave functions show broader spatial distributions and non-Gaussian structures than Gaussian ansätze with matching rms radius, suggesting a mechanism to address underestimation of A=4 cluster production.
pQCD plus flavor symmetry yields O(10^{-5}) branching ratios for selected B to baryon + dark baryon decays in Type-I and Type-II scenarios.
Using effective Lagrangians under molecular assumptions for η_c D* and J/ψ D*, the authors estimate B_c production branching ratios of 10^{-4} and 10^{-5} respectively, with decay widths O(MeV).
