Using the latest PandaX limits on the light dark matter(DM) with a light mediator, we check their implication on the parameter space of the general singlet extension of MSSM(without Z3 symmetry), which can have a sufficient DM self-interaction to solve the small-scale structure problem. We find that the PandaX limits can tightly constrain the parameter space, depending on the coupling λ between the singlet and doublet Higgs fields. For the singlet extension of MSSM with Z3 symmetry, the so-called NMSSM, we also demonstrate the PandaX constraints on its parameter space, which gives a light DM with the correct relic density but without sufficient self-interaction to solve the small-scale structure problem. We find that in NMSSM, the GeV dark matter with a sub-GeV mediator is tightly constrained.

Analytical formulae for the phase space factors and three-momenta of three-and four-body final states are derived for all sets of independent kinematic variables containing invariant mass *** formulae will help experimental physicists to perform data *** an example,we show how to use these formulae to distinguish the different mechanisms of the e+p→e+J/ψ+p process when searching the signals of P_(c) states in the energy region of the Electron-Ion collider at China(EicC).

In this study,we analyze the electroproduction of the LHCb pentaquark states with the assumption that they are resonant *** main concern is to investigate the final state distribution in the phase space to extract a feeble pentaquark signal from a large non-resonant *** results indicate that the signal to background ratio will increase significantly with a proper kinematic cut,which will be beneficial for future experimental analysis.

BACKGROUND Although skin avulsions to male external genitalia are rare, they can be both physically and psychologically traumatic. Thus, the necessity for judicious management poses significant challenges to surgeons in order to avoid potential permanent disabilities. We report a case of massive penoscrotal skin avulsion and a composite graft was creatively applied to cover the defect which achieved good results. We believe that this case is of great reference value for fellow *** SUMMARY A 52-year-old male presented with massive traumatic avulsion of the penile and scrotal skin following mishandling of an electric drill. The avulsed skin was missing. The patient was diagnosed with massive skin avulsion of external genitalia. Following initial complete debridement of devitalized or infected tissues, Pelnac dermal substitute was secured to the defect with the assistance of negative-pressure wound closure. In the final step, the silicone layer of Pelnac was removed and a split-thickness skin graft was applied. The defect had healed at the two-month follow-up. The patient now has normal erections and satisfactory sexual *** Our experience with this wound repair demonstrated that the combination of a dermal regeneration template and a split-thickness skin graft with vacuumassisted closure is a safe, well-tolerated and efficient solution for the reconstruction of massive penoscrotal skin defects.
