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 …

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 …

In this article, we propose the Δ 2 HDM S as a combined explanation of several excesses
and anomalies observed at the LHC. Especially, tt¯ differential distributions point towards …

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 …

We study the effect of an ultralight primordial black hole (PBH) dominated phase on the
gravitational wave (GW) spectrum generated by a cosmic string (CS) network formed as a …

Gravitational waves are a unique probe of the early Universe, as the Universe is transparent
to gravitational radiation right back to the beginning. In this article, we summarise detection …

A new precision measurement of the W boson mass has been announced by the CDF
collaboration, which strongly deviates from the Standard Model prediction. In this article, we …

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 …

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 …

We study the effects of vectorlike leptons on the W-boson mass in a model with a vectorlike
U (1)′ gauge symmetry. This model provides simultaneous explanations for the recent …
