In this talk I show that it is possible to find an upper bound on the total proton lifetime. I conclude that the simplest realistic non‐supersymmetric grand unified theory is based on SU(5) with a Higgs sector composed of 5H, 24H and 15H. I discuss the possibility to test this GUT scenario at the next generation of proton decay experiments and future colliders through the production of light scalar leptoquarks.

Upper bound on the mass of the type III seesaw triplet in an SU(5) model

We investigate correlation between gauge coupling unification, fermion mass spectrum, proton decay, perturbativity and ultraviolet cutoff within an SU(5) grand unified theory with minimal scalar

Lepton number violation and W ′ chiral couplings at the LHC

We study the observability for a heavy Majorana neutrino N along with a new charged gauge boson W′ at the LHC. We emphasize the complementarity of these two particles in their production and decay to

The Search for Heavy Majorana Neutrinos

The Majorana nature of neutrinos can be experimentally verified only via lepton-number violating processes involving charged leptons. We study 36 lepton-number violating (LV ) processes from the

A potential scenario for Majorana neutrino detection at future lepton colliders

A bstractThe existence of Majorana neutrinos must lead to lepton-number violating processes, and the Majorana nature of neutrinos can only be experimentally verified via lepton-number violating

Search for boosted Higgs boson and other resonances decaying into b-quark pairs using the ATLAS detector and studies of CMOS pixel sensors for the HL-LHC

In this thesis, two novel analyses looking for jets stemming from the hadronization of b-quarks are presented together with a detailed description of the tools and the related recent improvements for

Matrix element $U_{\tau N}$ of sterile neutrino N mixing with $\nu_{\tau}$ is the least constrained in the literature among the three $U_{\alpha N}$ ($\alpha=e,\mu,\tau$) mixing parameters

Neutrino Masses and Mixings in Gauge Models with Spontaneous Parity Violation

Unified electroweak gauge theories based on the gauge group SU(2)/sub L/ x SU(2)/sub R/ x U(1)/sub B/-L, in which the breakdown of parity invariance is spontaneous, lead most naturally to a massive

Is Baryon Number Conserved

We suggest that baryon-number conservation may not be absolute and that an integrally charged quark may disintegrate into two leptons and an antilepton with a coupling strength GBmp2≲10−9. On the
