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.

Where numerical weather prediction meets large‐eddy simulations in a convective boundary layer during the FESSTVaL field experiment

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We exploit the Field Experiment on Sub‐mesoscale Spatio‐Temporal Variability in Lindenberg (FESSTVaL) to compare the performance of an NWP model at sub‐km resolutions with a traditional LES model. Focusing on clear‐sky ABL turbulence (June 14), shallow convective clouds and surface radiation (June 27), and deep convective cold pools (June 29), we find ...

Crossing and Anticrossing of Exchange‐Coupled Molecular Spin Excitation Energy Levels

Small, EarlyView.
Orientation matters: The excitation energy levels of exchange‐coupled spins of two nickelocene molecules anchored to superconducting electrodes are explored via inelastic electron tunneling spectroscopy. Depending on the tilt angle of the single‐molecule magnetic probe the levels cross or exhibit avoided crossing. Abstract The superconducting Pb tip of

CP Violation for B0→ρ0(ω)ρ0(ω)→π+π-π+π- in QCD Factorization

Advances in High Energy Physics, 2014
In the QCD factorization (QCDF) approach we study the direct CP violation in B-0→ρ0(ω)ρ0(ω)→π+π-π+π- via the ρ-ω mixing mechanism. We find that the CP violation can be enhanced by double ρ-ω mixing when the masses of the π+π- pairs are in the vicinity of

Probing light top partners with CP violation

Journal of High Energy Physics, 2018
We investigate CP-violating effects induced by light top partners in composite Higgs theories. We find that sizable contributions to the dipole moments of the light SM quarks and leptons are generically generated at the two-loop level through Barr-Zee ...

CP Violation and Baryogenesis

, 2002
In these lecture notes an introduction is given to some ideas and attempts to understand the origin of the matter-antimatter asymmetry of the universe. After the discussion of some basic issues of cosmology and particle theory the scenarios of electroweak baryogenesis, GUT baryogenesis, and leptogenesis are outlined.

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.

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

Challenging Parole Decisions in England and Wales: Reconsideration and Set Aside

The Modern Law Review, EarlyView.
Of all the reforms to parole in England and Wales that were introduced after the furore surrounding the 2017 decision to direct the release of the so‐called ‘Black cab rapist’, John Worboys, perhaps the most important was the creation in 2019 of a reconsideration mechanism which obliges the Parole Board (on application) to take a second look at ...

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 ...
