Abstract We revisit the gauged U(1) B−L explanation of the ATOMKI nuclear anomalies, in which the new gauge boson is the hypothetical X(17) particle. It is known that the vanilla B − L scenario is unable to account for appropriate couplings, name

Abstract The Two Higgs Doublet Model invariant under the gauge group $$SU(2)\times U(1)$$ S U ( 2 ) × U ( 1 ) is known to have six additional global discrete or continuous symmetries of its scalar sector. We have discovered regions of parameter spac

Introduction Individuals experiencing psychotic symptoms often lack insight into their conditions, especially in first psychotic episodes. According to the Portuguese Mental Health Law, involuntary hospitalization may be necessary in cases of severe

Introduction Individuals with mental health disorders often lack access to appropriate care, including psychosocial rehabilitation programs, which are considered essential for their recovery. In 2019, as part of the intervention by the Community and

Abstract In both Run 1 and Run 2 of the LHC, the CMS collaboration has observed an excess of events in the searches for low-mass Higgs bosons in the diphoton final state at a mass of about 95 GeV. After a recent update of the experimental analysis, i

Abstract Soft breaking of a symmetry requires an invariance of the dimension-4 part of the Lagrangian and non-trivial variation of the lower-dimensional part. However, in general, separation between the dim-4 and lower-dimensional Lagrangian is not i

Abstract Scalar triplet extensions of the Standard Model provide an interesting playground for the explanation of neutrino mass suppression through the type-II seesaw mechanism. Propelled by the possible connections with leptonic CP violation, we exp

Abstract We construct a three-Higgs doublet model with a flavour non-universal U(1) × ℤ2 symmetry. That symmetry induces suppressed flavour-changing interactions mediated by neutral scalars. New scalars with masses below the TeV scale can still su

Abstract Platelet-derived extracellular vesicles (PDEVs) are the most abundant amongst all types of EVs in the circulation. However, the mechanisms leading to PDEVs release, their role in coagulation and phenotypic composition are poorly understood.
