The observed pattern of fermion masses and mixing is an outstanding puzzle in particle
physics, generally known as the flavor problem. Over the years, guided by precision neutrino …

The fourth edition of this well-established, highly regarded two-volume set continues to
provide a fundamental introduction to advanced particle physics while incorporating …

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 consider a type I or type X two Higgs doublets model with a modified lepton sector. The
generalized lepton sector is also flavor conserving but with the new Yukawa couplings …

Detector simulation is a key component for studies on prospective future high-energy
colliders, the design, optimization, testing and operation of particle physics experiments, and …

In this paper, we work with 16 different single scalar particle extensions of the Standard
Model. We present the sets of dimension-six effective operators and the associated Wilson …

A bstract In the presence of axions or axion-like particles (ALPs) that couple to the Standard
Model via dimension-five interactions, dimension-six SMEFT interactions are generated via …

A bstract We introduce the first family of parton showers that achieve next-to-leading
logarithmic (NLL) accuracy for processes involving a t-channel exchange of a colour-singlet …

A bstract We perform a comprehensive study of the allowed parameter space of the Two
Higgs Doublet Model of Type II (2HDM-II). Using the theoretical framework flavio we …

In the last decades, the Standard Model (SM) of particle physics has been extensively tested
and confirmed, with the announced discovery of the Higgs boson in 2012 being the last …
