Large Matter Effects in ! Oscillations

چکیده
0031-9007= We show that matter effects change the ! oscillation probability by as much as 70% for certain ranges of energies and path lengths. Consequently, the ! survival probability also undergoes large changes. A proper understanding of survival rates must consider matter effects in P as well as P e. We comment on (a) how these matter effects may be observed and the sign of 31 determined in atmospheric neutrino measurements and at neutrino factories, and (b) how they lead to heightened sensitivity for small 13.

Matter effects in oscillations of neutrinos traveling short distances in matter
It is well known that when the distance t traveled by neutrinos in matter is short, matter effects in oscillations of neutrino flavour are small and decrease with decreasing t more rapidly than the oscillations effects themselves. We discuss the reason for this and demonstrate that under certain circumstances this statement is no longer correct. In particular, we show that if neutrinos propagat...
متن کاملFormation of Large Structures in the Acceleration Universe with a Hybrid Expansion Law
In the current paper, we have studied the effect of dark energy on for-mation where dark energy exists in the background. For this purpose, we used both WMAP9 and Planck data to study how the radius changes with redshift in these mod-els. We used different data sets to fix the cosmological parameters to obtain a solution for a spherical region under collapse. The mechanism of structure formation f...
متن کاملMatter effects in short-baseline neutrino oscillations
It is well known that matter effects in short-baseline oscillations of neutrino flavour are small and decrease with decreasing baseline more rapidly than the oscillations effects themselves. We discuss the reason for this and demonstrate that under certain circumstances this statement is no longer correct. In particular, we show that if neutrinos propagate significant distances in vacuum before...
متن کاملNonlinear magnetotransport theory and Hall induced resistance oscillations in graphene.
The quantum oscillations of nonlinear magnetoresistance in graphene that occur in response to a dc current bias are investigated. We present a theoretical model for the nonlinear magnetotransport of graphene carriers. The model is based on the exact solution of the effective Dirac equation in crossed electric and magnetic fields, while the effects of randomly distributed impurities are perturba...
متن کاملNeutrino Oscillations beyond Two Flavours
I review some theoretical aspects of neutrino oscillations in the case when more than two neutrino flavours are involved. These include: approximate analytic solutions for 3-flavour (3f) oscillations in matter; matter effects in νµ ↔ ντ oscillations; 3f effects in oscillations of solar, atmospheric, reactor and supernova neutrinos and in accelerator long-baseline experiments; CP and T violation...
متن کاملEffects of Geometric Nonlinearity on Stress Analysis in Large Amplitude Vibration of Moderately Thick Annular Functionally Graded Plate
This paper deals with the nonlinear free vibration of thick annular functionally graded material plates. The thickness is assumed to be constant. Material properties are assumed to be graded in the thickness direction according to a simple power law distribution in terms of the volume fractions of the constituents. The formulations are based on the first-order shear deformation plate theory and...
