triplet scalar as the origin of the 95 GeV excess?
S Ashanujjaman, S Banik, G Coloretti, A Crivellin… - Physical Review D, 2023 - APS
We explore the possibility that an SU (2) L triplet scalar with hypercharge Y= 0 is the origin of
the 95 GeV diphoton excess. For a small mixing angle with the Standard Model Higgs, its …

Gravitational wave signatures of a PBH-generated baryon-dark matter coincidence
We propose a new way of probing the nonthermal origin of baryon asymmetry of the
Universe (BAU) and dark matter (DM) from evaporating primordial black holes (PBHs) via …

Monopoles, strings and gravitational waves in non-minimal inflation
We discuss how in SO (10) grand unification an observable number density of topologically
stable intermediate mass (∼ 10 14 GeV) monopoles survive inflation driven by a Coleman …

Minimal model for the -boson mass, , , and quark-mixing-matrix unitarity
A Crivellin, M Kirk, A Thapa - Physical Review D, 2023 - APS
The SU (2) L triplet scalar with hypercharge Y= 0 predicts a positive definite shift in the W
mass, with respect to the Standard Model prediction, if it acquires a vacuum expectation …

Muon and -mass anomalies explained and the electroweak vacuum stabilized by extending the minimal type-II seesaw model
N Chakrabarty - Physical Review D, 2023 - APS
The recent precise measurement of the W-mass by the CDF II Collaboration could be
indicative of new physics beyond the Standard Model. On the other hand, a resolution of the …
