Anomalous extension of the Standard Model

Pascal Anastasopoulos, Ignatios Antoniadis, Karim Benakli +1

We present a set of example models in which the Standard Model (SM) symmetry group is extended by a new abelian symmetry. This additional symmetry appears anomalous in the effectiv…

Reheating and Leptogenesis after Vector inflation

Simon Cléry, Pascal Anastasopoulos, Yann Mambrini

We study the reheating and non-thermal leptogenesis in the case of a vector inflaton. We concentrate on particle production during the phase of oscillating background, especially g…

Anomalous and axial Z' contributions to g-2

Pascal Anastasopoulos, Kunio Kaneta, Elias Kiritsis +1

We study the effects of an anomalous Z' boson on the anomalous magnetic moment of the muon (g-2), and especially the impact of its axial coupling. We mainly evaluate the negative c…

Light stringy states and the of the muon

Pascal Anastasopoulos, Elias Niederwieser, François Rondeau

In this work, we evaluate the contributions to the anomalous magnetic moment of the muon () coming from light stringy states in a D-brane semi-realistic configuration. A s…

Emergent neutrinos from heavy messengers

Pascal Anastasopoulos, Elias Kiritsis

Fermionic bound states (mesinos) of messengers can play the role of right-handed neutrinos and due to their heavy masses they can realize the seesaw mechanism providing light and h…

Lifetimes of light stringy states

Pascal Anastasopoulos, Elias Niederwieser

In this paper, we evaluate the lifetime of the light stringy states that emerge in intersecting D-brane realisations of the Standard Model. For concreteness, we focus on a light ma…
