We review various aspects of de Sitter spacetime in string theory: its status as an Effective
Field Theory spacetime solution, its relation to the vacuum energy problem in string theory …

A bstract If neutrino masses arise from a TeV-scale minimal Left-Right seesaw model, the
ensuing extended Higgs sector with neutral, singly and doubly-charged scalars has a …

We demonstrate a model which captures certain attractive features of SU (5) theory, while
providing a possible escape from proton decay. In this paper we show how ladder operators …

We review the approach to the Standard Model of particle interactions based on spectral
noncommutative geometry. The paper is (nearly) self-contained and presents both the …

Majorana neutrinos naturally lead to a lepton number violation (LNV). A superposition of
Majorana states can mimic Dirac-type neutrinos, leading to lepton number conservation …

This is a survey of the historical development of the spectral Standard Model and beyond,
starting with the ground breaking paper of Alain Connes in 1988 where he observed that …

A bstract Motivated by possible scalar-leptoquark explanations of the recently reported B-
decay anomalies, we investigate whether the required leptoquarks can be accommodated …

A bstract We analyze the running at one-loop of the gauge couplings in the spectral Pati-
Salam model that was derived in the framework of noncommutative geometry. There are a …

A bstract We demonstrate that the relic gravitational wave background from a multi-step
phase transition may deviate from the simple sum of the single spectra, for phase transitions …

A bstract We show how twisting the spectral triple of the Standard Model of elementary
particles naturally yields the Krein space associated with the Lorentzian signature of …
