Nonadiabatic Induced Dipole Moment by High Intensity Femtosecond Optical Pulses [PDF]

open access: yesApplied Physics B - Lasers and Optics, 78, 821 (2004), 2006
Nonadiabtic dressed states and nonadiabatic induced dipole moment in the leading order of nonadiabaticity is proposed. The nonadiabatic induced dipole moment is studied in the femtosecond time domain.

Evaluation of an EPID in vivo monitoring system using local and external independent audit measurements

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose The aim of this work was to evaluate the SunCHECK PerFRACTION, the software for in vivo monitoring using EPID images. Materials/Methods First, the PerFRACTION ability to detect errors was investigated simulating two situations: (1) variation of LINAC output and (2) variation of the phantom thickness.

Digital radiography image quality evaluation using various phantoms and software

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose To investigate the effect of the exposure parameters on image quality (IQ) metrics of phantom images, obtained automatically using software or from visual evaluation. Methods Three commercial phantoms and a homemade phantom constructed according to the instructions given in the IAEA Human Health Series No.

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.

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.

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.

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 ...

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
