Bounds on Bosonic Topcolor [PDF]

, 2000
We consider the phenomenology of models in which electroweak symmetry breaking is triggered by new strong dynamics affecting the third generation and is transmitted to the light fermions via a fundamental Higgs doublet. While similar in spirit to the old

Lepton-flavor universality violation in R K and R D ∗ $$ {R}_{D^{{}_{\left(\ast \right)}}} $$ from warped space

Journal of High Energy Physics, 2017
Some anomalies in the processes b → sℓℓ (ℓ = μ, e) and b → c ℓ ν ¯ ℓ $$ b\to c\ell {\overline{\nu}}_{\ell } $$ (ℓ = τ, μ, e), in particular in the observables R K and R D ∗ $$ {R}_{D^{{}_{\left(\ast \right)}}} $$ , have been found by the BaBar, LHCb and ...

Fermion mass hierarchy and phenomenology in the 5D Domain Wall Standard Model

Journal of High Energy Physics, 2019
We have recently proposed a setup of the “Domain-Wall Standard Model” in 5D spacetime, where all the Standard Model (SM) fields are localized in certain domains of the extra 5th dimension.

A Clockwork Theory [PDF]

, 2016
The clockwork is a mechanism for generating light particles with exponentially suppressed interactions in theories which contain no small parameters at the fundamental level.

Exact greybody factors for the brane scalar field of five-dimensional rotating black holes

Journal of High Energy Physics, 2019
We study scalar perturbations of the five-dimensional rotating black holes and find an exact solution giving exact description of the Hawking radiation.

Dark bubbles: decorating the wall

Journal of High Energy Physics, 2020
Motivated by the difficulty of constructing de Sitter vacua in string theory, a new approach was proposed in arXiv:1807.01570 and arXiv:1907.04268 , where four dimensional de Sitter space was realized as the effective cosmology, with matter and radiation,

Bubble needs strings

Journal of High Energy Physics, 2021
In this paper, we want to emphasize the pivotal role played by strings in the model realizing de Sitter using an expanding bubble, proposed and subsequently developed in [1–3].

Inflation Dynamics and Reheating [PDF]

, 2005
We review the theory of inflation with single and multiple fields paying particular attention to the dynamics of adiabatic and entropy/isocurvature perturbations which provide the primary means of testing inflationary models.

R D * $$ {R}_{D^{\left(*\right)}} $$ in custodial warped space

Journal of High Energy Physics, 2018
Flavor physics experiments allow to probe the accuracy of the Standard Model (SM) description at low energies, and are sensitive to new heavy gauge bosons that couple to quarks and leptons in a relevant way.

Neutrino oscillations and large extra dimensions

, 2000
Assuming that right-handed neutrinos exist and propagate in some large extra dimensions, we attempt to give a comprehensive description of the phenomenology of neutrino oscillations.
