Searching for axion-like particles with proton tagging at the LHC
Journal of High Energy Physics, 2018 The existence of an axion-like particle (ALP) would induce anomalous scattering of light by light. This process can be probed at the Large Hadron Collider in central exclusive production of photon pairs in proton-proton collisions by tagging the ...

De Sitter cosmology on an expanding bubble
Journal of High Energy Physics, 2019 Constructing an explicit compactification yielding a metastable de Sitter (dS) vacuum in a UV consistent string theory is an incredibly difficult open problem.

Possibility of hypothetical stable micro black hole production at future 100 TeV collider
European Physical Journal C: Particles and Fields, 2017 We study the phenomenology of TeV-scale black holes predicted in theories with large extra dimensions, under the further assumption that they are absolutely stable. Our goal is to present an exhaustive analysis of safety of the proposed 100 TeV collider,

Heavy photophilic scalar at the LHC from a varying electromagnetic coupling
Nuclear Physics B, 2017 We investigate the phenomenology of a heavy scalar ϕ of the type involved in Bekenstein's framework for varying electromagnetic coupling theories, with the difference that the scalar in our model has a large mass.

Extra dimensions hypothesis in high energy physics
EPJ Web of Conferences, 2017 We discuss the history of the extra dimensions hypothesis and the physics and phenomenology of models with large extra dimensions with an emphasis on the Randall- Sundrum (RS) model with two branes. We argue that the Standard Model extension based on the

Exploring non minimal Universal Extra Dimensional model at the LHC
Journal of High Energy Physics, 2018 We study the collider phenomenology of non minimal universal extra dimensional (nmUED) model in the context of the Large Hadron Collider at CERN. nmUED is an incarnation of the Standard Model in 4 + 1 space-time dimensions compactified on an S 1/Z 2 ...

On small Dirac neutrino masses in string theory
Journal of High Energy PhysicsWe study how tiny Dirac neutrino masses consistent with experimental constraints can arise in string theory SM-like vacua. We use as a laboratory 4d N $$ \mathcal{N} $$ = 1 type IIA Calabi-Yau orientifold compactifications, and in particular recent ...

Revisiting universal extra-dimension model with gravity mediated decays
Journal of High Energy PhysicsWe explore the collider phenomenology of the fat-brane realization of the Minimal Universal Extra Dimension (mUED) model, where Standard Model (SM) fields propagate in a small extra dimension while gravity accesses additional large extra dimensions. This

Phenomenology of Hyperbolic Large Extra Dimensions for Hadron Colliders
, 2007 The subject of extra dimensions has experienced a renewed interest in recent years. Arkani-Hamed, Dimopoulos, and Dvali (ADD) have pointed out that it is possiblethat there exist extra dimensions that are as large as micrometer sized, if theStandard Model fields are restricted to a four-dimensional brane.

Yukawa couplings at infinite distance and swampland towers in chiral theories
Journal of High Energy PhysicsWe study limits of vanishing Yukawa couplings of 4d chiral matter fields in Quantum Gravity, using as a laboratory type IIA orientifolds with D6-branes.
