We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a
comprehensive survey of standard model (SM) extensions. LLPs are a common prediction of …

We review scenarios in which the particles that account for the Dark Matter (DM) in the
Universe interact only through their couplings with the Higgs sector of the theory, the so …

A bstract We perform a global fit of electroweak data, finding that the anomaly in the W mass
claimed by the CDF collaboration can be reproduced as a universal new-physics correction …

We show that the recent detection of a gravitational wave (GW) background reported by
various pulsar timing array (PTA) collaborations including NANOGrav-15 yr, PPTA …

A bstract We extract from data the parameters of the Higgs potential, the top Yukawa
coupling and the electroweak gauge couplings with full 2-loop NNLO precision, and we …

A bstract We present the first complete next-to-next-to-leading order analysis of the Standard
Model Higgs potential. We computed the two-loop QCD and Yukawa corrections to the …

The current flow of high accuracy astrophysical data, among which are the Cosmic
Microwave Background (CMB) measurements by the Planck satellite, offers an …

A bstract We propose a minimal extension of the standard model which includes only one
additional complex scalar field, flavon, with flavor-dependent global U (1) symmetry. It not …

We present a minimal extension of the Standard Model (SM) providing a consistent picture
of particle physics from the electroweak scale to the Planck scale and of cosmology from …

Abstract Models with non-minimal Higgs sectors represent a mainstream direction in
theoretical exploration of physics opportunities beyond the Standard Model. Extended scalar …
