Matter-parity as a residual gauge symmetry: Probing a theory of cosmological dark matter

open access: yesPhysics Letters B, 2017
We discuss a non-supersymmetric scenario which addresses the origin of the matter-parity symmetry, PM=(−1)3(B−L)+2s, leading to a viable Dirac fermion dark matter candidate.

Searching for New Physics Through AMO Precision Measurements

open access: yes, 2012
We briefly review recent experiments in atomic, molecular, and optical physics using precision measurements to search for physics beyond the Standard Model.

Dynamical CP Violation and Flavour-Changing Processes [PDF]

open access: yes, 2001
We investigate the phenomenological constraints on a model where, besides the standard model Higgs sector, there is an effective new strong interaction acting on the third generation of quarks and characterized by a $\theta$-like term. This $\theta$ term

Electric dipole moments and the search for new physics

open access: yes, 2022
Static electric dipole moments of nondegenerate systems probe mass scales for physics beyond the Standard Model well beyond those reached directly at high energy colliders. Discrimination between different physics models, however, requires complementary searches in atomic-molecular-and-optical, nuclear and particle physics.

formulation of the first principles in Physics I 7 in light of the notion of generation

open access: yesEstudios de Filosofía, 2021
In the present work we are interested in analyzing how Aristotle formulates the principles of physics from the notion of generation. Our thesis is that Physics I 7 is the “moment” of euporia that closes a process beginning in 1-2 with the ...

Enhancement of Radiatively Induced Magnetic Moment Form-Factors of Muon: an Effective Lagrangian Approach [PDF]

open access: yes, 2001
Using an effective lagrangian approach, we identify a class of models in which the loop-induced magnetic moment form-factors of muon are enhanced by possibly large factors (\Lambda^2_F/\Lambda^2)(m_\tau/m_\mu)\ln(m_\tau^2/\Lambda^2) or (\Lambda^2_F ...

Electric dipole moments in a leptoquark scenario for the B-physics anomalies [PDF]

open access: yesJournal of High Energy Physics, 2020
Abstract Vector leptoquarks can address the lepton flavor universality anomalies in decays associated with the b → cℓν and b → sℓℓ transitions, as observed in recent years. While not required to explain the anomalies, these leptoquarks generically yield new sources of CP violation.

Muon g − 2: A review

open access: yesNuclear Physics B, 2022
The muon magnetic anomaly, aμ=(gμ−2)/2, plays a special role in the history of the Standard Model (SM). Precise calculations and measurements of this fundamental quantity provide a stringent test of the SM and a window to the physics beyond.

How Magnetic is the Neutrino?

open access: yes, 2007
The existence of a neutrino magnetic moment implies contributions to the neutrino mass via radiative corrections. We derive model-independent "naturalness" upper bounds on the magnetic moments of Dirac and Majorana neutrinos, generated by physics above ...
