CP Violation in Top Physics

, 2000
CP violation in top physics is reviewed. The Standard Model has negligible effects, consequently CP violation searches involving the top quark may constitute the best way to look for physics beyond the Standard Model. Non-standard sources of CP violation

Conformational bifurcation drives dual transport regimes in molecular junctions: Unsupervised machine learning insights

Smart Molecules, EarlyView.
Conformational bifurcation in n‐alk‐1‐yne molecular junctions drives dual transport regimes, with unsupervised machine learning and XPS revealing distinct planar and skewed conformers influencing conductance and tunneling efficiency. This discovery highlights anchor‐group control as a key design principle for tailoring molecular electronic devices ...

Cp violation analysis of $$D^0\rightarrow M^0 K \rightarrow M^0(\pi ^\pm \ell ^\mp \nu )$$ D 0 → M 0 K → M 0 ( π ± ℓ ∓ ν )

European Physical Journal C: Particles and Fields
CP violation in the charm sector is highly sensitive to new physics due to its small predicted value within the standard model. By this work, we investigated the CP violation in the cascade decay process $$D^0(t_1) \rightarrow \pi ^0 K(t_2) \rightarrow ...

CP violation and gravity as the weakest force [PDF]

, 2008
We argue that CP violation has rather dramatic impact on the "gravity as the weakest force" conjecture. Namely we find that new ultraviolet scale must be $\Lambda \lesssim \theta g^3 M_P$, where $\theta$ is an effective parameter describing CP violation ...

Plate tectonics in the microscopy realm: Molecular insights into morphological variability of Peridinium willei (Peridiniales, Dinophyceae)

TAXON, EarlyView.
Abstract Freshwater Peridinium willei (Peridiniaceae) is globally distributed, but reports linking its morphologies with DNA sequence data remain scarce. The taxonomy of the species, and its infraspecific taxa, remain ambiguous due to the lack of DNA sequence data for the original and type material.

CP violation induced by the double resonance for pure annihilation decay process in perturbative QCD

European Physical Journal C: Particles and Fields, 2017
In a perturbative QCD approach we study the direct CP violation in the pure annihilation decay process of $$\bar{B}^0_{s}\rightarrow \pi ^+\pi ^-\pi ^+\pi ^-$$ B ¯ s 0 → π + π - π + π - induced by the $$\rho $$ ρ and $$\omega $$ ω double resonance effect.

Spontaneous CP violation in multi-Higgs potentials with triplets of Δ(3n 2) and Δ(6n 2)

Journal of High Energy Physics, 2017
Motivated by discrete flavour symmetry models, we analyse Spontaneous CP Violation (SCPV) for potentials involving three or six Higgs fields (both electroweak doublets and singlets) which fall into irreducible triplet representations of discrete ...

Public Tax Disclosures and Investor Perceptions Publications d'informations fiscales et perceptions des investisseurs

Contemporary Accounting Research, EarlyView.
ABSTRACT Regulators are increasingly considering and mandating additional public tax disclosures to enhance transparency and promote scrutiny of corporate tax avoidance. We conducted three experiments to examine how such disclosures influence retail investors' perceptions of firms with identical effective tax rates but different tax avoidance methods ...

Overview of LHCb results on CP violation

EPJ Web of Conferences, 2014
Precision measurements of CP violating observables in the mixing and decay of B mesons provide excellent opportunities to search for possible contributions from New Physics beyond the Standard Model. In this contribution, key measurements pur-sued by the

Sphalerons with CP-Violating Higgs Potentials

, 1998
We investigate the effect on the sphaleron in the two Higgs doublet electroweak theory of including CP violation in the Higgs potential. To have better control over the relation between the sphaleron energy and the physical quantities in the theory, we ...
