Physics of collisionless phase mixing [PDF]

open access: yesPhysics of Plasmas, 2008
Previous studies of phase mixing of ion cyclotron (IC), Alfvénic, waves in the collisionless regime have established the generation of parallel electric field and hence acceleration of electrons in the regions of transverse density inhomogeneity. However, outstanding issues were left open.

Flavor physics in the quark sector [PDF]

open access: yes, 2008
In the past decade, one of the major challenges of particle physics has been to gain an in-depth understanding of the role of quark flavor. In this time frame, measurements and the theoretical interpretation of their results have advanced tremendously. A

Simulating microstructure evolution during passive mixing [PDF]

open access: yes, 2011
The prediction of microstructure evolution during passive mixing is of major interest in order to qualify and quantify mixing devices as well as to predict the final morphology of the resulting blend.

B physics beyond the Standard Model at one loop: complete renormalization group evolution below the electroweak scale

open access: yesJournal of High Energy Physics, 2017
General analyses of B-physics processes beyond the Standard Model require accounting for operator mixing in the renormalization-group evolution from the matching scale down to the typical scale of B physics.

Strange processes in general two Higgs doublet model

open access: yesJournal of High Energy Physics, 2022
In the general two Higgs doublet model (g2HDM) that has extra Yukawa couplings, we analyze their New Physics (NP) contributions to kaon mixing parameter ε K , direct CP violation parameter ε′/ε, and rare K + → π + ν ν ¯ $$ {K}^{+}\to {\pi}^{+}\nu ...

Spectrally resolved wave-mixing between near- and far-infrared pulses in gas [PDF]

open access: yes, 2013
We investigate the nonlinear wave-mixing in gases between intense, short optical pulses and long-wavelength fields (mid infrared and terahertz). We show numerically that the beating between the sum- and difference-frequency generation components can be ...

Flavor signatures of isosinglet vector-like down quark model

open access: yesNuclear Physics B, 2016
We consider a model where the standard model is extended by the addition of a vector-like isosinglet down-type quark b′. We perform a χ2 fit to the flavor physics data and obtain the preferred central values along with errors of all the elements of the ...

Precision measurement of the B[0 over s]–[– over B][0 over s] oscillation frequency with the decay B[0 over s]→D[– over s]π[superscript +] [PDF]

open access: yes, 2013
A key ingredient to searches for physics beyond the Standard Model in B[0 over s] mixing phenomena is the measurement of the B[0 over s]–[– over B][0 over s] oscillation frequency, which is equivalent to the mass difference Δm[subscript s] of the B[0 ...

The Effect of Mixing Nanoparticles on the Suspension Physical Stability

open access: yesKuwait Journal of Science, 2022
Energy transfer in a hybrid mixture of Rhodamine 6G (Rh6G) dye laser as a donor and nanoparticles (NPs) as an acceptor were studied. The absorption spectra of 1×10-5M of Rh6G in Distilled Water show increase in the intensity when adding NPs. noticeable, improve the spectra when adding Aluminum Oxide Al2O3 NPs. Adding NPs quench the fluorescence spectra

Measurement of mixing and CP violation parameters in two-body charm decays [PDF]

open access: yes, 2012
A study of mixing and indirect CP violation in D 0 mesons through the determination of the parameters y CP and A Γ is presented. The parameter y CP is the deviation from unity of the ratio of effective lifetimes measured in D 0 decays to the CP ...
