CP violation in the grimus-neufeld model /
… This is closely related to the topic of CP violation, which refers to the phenomenon when the same processes treat matter and antimatter particles differently. Searching for the sources of CP violation inevitably leads to expansions of the Standard Model by new particles and interactions. …

CP-Violation and Baryogenesis on Electroweak Scales
In this work we study different aspects of CP-violation on electroweak scales and in this context quantum transport in electroweak baryogenesis. First we focus on CP-violation of CKM type as it is present in the Standard Model. We explain basic concepts and the reason for the smallness of …

Violation of CP invariance in weak interactions
… F-spin currents of the SU, current algebra. Both CP conserving and CP violating non-leptonic processes are generated by the same primary interaction. This interaction is used to calculate the s-wave amplitudes of hyperon non-leptonic decays, the K1 -> 2pi decay rate and the decay rate of the CP …

Parallel Gauss-Newton method for CP decomposition
… to Alternating least squares algorithm for CP decomposition. Alternating least squares may exhibit slow or no convergence, especially when high accuracy is required. CP decomposition problem can be formulated as a non-linear least squares problem to apply iterative Newton-like methods. …

Study of CP-violation at the Belle experiment
We present a first measurement of time-dependent CP-violation in B0 → D∗∓ ρ± , where D∗∓ → D0 π. The analysis was performed using the final Belle dataset containing 772 × 106 B ¯B pairs collected at the KEKB e+ e− collider. Three D0 decay modes are analyzed, K∓ π± , K∓ π± π0 , and K∓ π± π∓ π± . …

Acenaphthylene Based CP-PAH Materials for Organic Semiconductors
Organic-based electronic devices have received considerable attention because of their presumable advantages over traditional inorganic-based electronics, such as low cost, flexibility, and applicability for large area production. Because of the possible commercialization of electronic products …

CP-violation in cascade decays at the LHC
We study the potential to observe CP-violating effects in various supersymmetric cascade decay chains at the LHC. Asymmetries composed by triple products of momenta of the final state particles are sensitive to CP-violating effects. We analytically calculate the cascade decays including the …

CP violation in production and decay of supersymmetric particles
In dieser Dissertation untersuchen wir CP verletzende Effekte von MSSM-Phasen in Produktion und Zwei-Teilchen-Zerfaellen von Neutralinos, Charginos und Sfermionen. Fuer verschiedene supersymmetrische Prozesse definieren und berechnen wir CP-ungerade Asymmetrien, welche auf Spatprodukten basieren. …

Nonlinear waves in systems with PT/CP - symmetric potentials
… an optical emulation of the Charge-Parity (CP) symmetry. The addition of the intra-core cubic nonlinearity, despite breaking the CP-symmetry, gives rise to several families of fundamental bright discrete solitons, whose existence and stability are explored here by means of analytical and …

Spontaneous CP-Violation in Two Higgs Doublet Supersymmetric Models
An alternative approach to the problem of CP-violation is presented. It is based on the possibility of spontaneous CP-breakdown in models with two Higgs doublets. General features of the phenomenon such as stability of the vacuum and the existence of a light axion are discussed. We investigate the …

Search For Cp Violation In Singly Cabibbo-Suppressed Charm Decays
<p>CP violation in singly Cabibbo-Suppressed (SCS) weak decays of charged D mesons is predicted in the Standard Model (SM) to have asymmetries on the order of $10^{-3}$. $CP$ violation has not yet been observed in the Charm sector; however, the BaBar experiment now has extremely large data samples …

Intermolecular C-H activation effected by CP*W(NO)-containing complexes
Thermolysis of Cp*W(NO)(CH₂CMe₃)₂ (2.1) in halo, methoxy, or phenylethynyl-substituted benzenes leads to the formation of the alkylidene intermediateCp*W(NO)(=CHCMe₃) which selectively activates ortho C-H bonds of the organicsubstrates. The ortho-regioselectivity diminishes as the size of the …
