Beautiful CP violation

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1998
CP violation is observed to date only in K^0 decays and is parameterizable by a single quantity epsilon. Because it is one of the least understood phenomena in the Standard Model and holds a clue to baryogenesis, it must be investigated further. Highly specialized searches in K^0 decays are possible. Effects in B decays are much larger.

Are There Causal Associations Between Obsessive‐Compulsive Disorder and Cardiometabolic Phenotypes? A Genetic Correlation and Bi‐Directional Mendelian Randomization Study

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT In epidemiological studies, obsessive‐compulsive disorder (OCD) is robustly associated with increased risk of cardiometabolic disorders, including cardiovascular diseases, type 2 diabetes, and obesity. However, the mechanisms behind these associations are unclear. We conducted genetic correlation analyses to explore shared genetic etiology and

Soft CP violation in K-meson systems

open access: yes, 2005
We consider a model with soft CP violation which accommodate the CP violation in the neutral kaons even if we assume that the Cabibbo-Kobayashi-Maskawa mixing matrix is real and the sources of CP violation are three complex vacuum expectation values and ...

Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

open access: yesChemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Baryogenesis from primordial CP violation

open access: yesJournal of High Energy Physics
We present a novel baryogenesis mechanism in a three-Higgs doublet model. The lightest doublet plays the role of the standard Higgs, and there are two heavier Higgs bosons.

CP violation of the loop induced H± → W±Z decays in the general two Higgs doublet model* [PDF]

open access: yesEPJ Web of Conferences
New sources of CP violation are necessary to solve the problem of the baryon asymmetry of the Universe. Extending the Higgs sector is one way to introduce such new CP violating phases, and studying observables resulting from the CP violation is important

CP violation in gauge theories [PDF]

open access: yes, 2000
We define the CP transformation properties of scalars, fermions and vectors in a gauge theory and show that only three types of interactions can lead to CP violation: scalar interactions, fermion-scalar interactions and $ F \tilde F $ associated with the

Accelerating Generic Long‐Acting Antiretrovirals for Global HIV Treatment: Workshop Findings and a Roadmap to Access

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
The global HIV response aims for widespread availability of affordable, quality‐assured long‐acting antiretroviral (LA ARV) drugs to achieve sustained epidemic control, particularly in low‐ and middle‐income countries. This report summarizes key discussion points, findings, and outcomes from an international workshop on generic LA ARVs, held in ...

A natural model of spontaneous CP violation

open access: yesJournal of High Energy Physics, 2022
We examine the possibility of building a natural non-supersymmetric model of spontaneous CP violation equipped with the Nelson-Barr (NB) mechanism to address the strong CP problem.

CP violation in a multi-Higgs doublet model with flavor changing neutral current

open access: yes, 1993
We study CP violation in a multi-Higgs doublet model based on a $S_3 \times Z_3$ horizontal symmetry where CKM phase is not the principal source of CP violation.
