Abstract The Standard Model lacks an organizing principle to describe quark and lepton
“flavours”. Neutrino oscillation experiments show that leptons mix very differently from …

The discovery of nonzero neutrino masses is among the most important particle physics
results of the last two decades: It indicates that the Standard Model of particle physics is …

A bstract The gauge-invariant operators up to dimension six in the low-energy effective field
theory below the electroweak scale are classified. There are 70 Hermitian dimension-five …

A bstract We compute the one-loop anomalous dimensions of the low-energy effective
Lagrangian below the electroweak scale, up to terms of dimension six. The theory has 70 …

We propose a novel way of probing high-scale Dirac leptogenesis, a viable alternative to the
canonical leptogenesis scenario where the total lepton number is conserved, kee** light …

This report summarizes the present status of neutrino non-standard interactions (NSI). After
a brief overview, several aspects of NSIs are discussed, including connection to neutrino …

A bstract The low-energy effective field theory below the electroweak scale (LEFT) describes
the effects at low energies of both the weak interaction and physics beyond the Standard …

The difference between baryon number B and lepton number L is the only anomaly-free
global symmetry of the Standard Model, easily promoted to a local symmetry by introducing …

If neutrinos are truly Dirac fermions, the smallness of their masses may still be natural if
certain symmetries exist beyond those of the standard model of quarks and leptons. We …

Planned CMB Stage IV experiments have the potential to measure the effective number of
relativistic degrees of freedom in the early Universe, N eff, with percent-level accuracy. This …
