Γ agreement experimental value lap chiral perturbation theory the dispersion relation
2014/12/23
Agreement between the experimental value Γ(KS→γγ) and the number predicted via a one-loop chiral perturbation theory calculation has been cited as a success for the latter. On the other hand the one-l...
THE REACTIONS GAMMA-GAMMA-]WL(+)WL(-) AND GAMMA-GAMMA-]Z(L)Z(L) IN SU(N) STRONGLY INTERACTING THEORIES
Low energy inflation models fermion
2014/12/23
In theories in which the parameters of the low energy theory are not unique, perhaps having different values in different domains of the universe as is possible in some inflationary models, the fermio...
Measurement of the γ3π process has revealed a possible conflict with what should be a solid prediction generated by the chiral anomaly. We show that inclusion of appropriate energy-momentum dependence...
Final state rescattering as a contribution to B->rho gamma
Radiation gamma $$$gamma scattering
2014/12/22
We provide a new estimate of the long-distance component to the radiative transition $B \to \rho \gamma$. Our mechanism involves the soft-scattering of on-shell hadronic products of nonleptonic $B$ de...
K-L->pi(0)gamma e(+)e(-) and its relation to CP and chiral tests
Decay in Kuala Lumpur non radiation chiral perturbation theory the quantitative easing policy
2014/12/22
The decay KL→π0γe+e- occurs at a higher rate than the nonradiative process KL→π0e+e-, and hence can be a background to CP violation studies using the latter reaction. It also has interest in its own r...
Chiral predictions for K-L ->pi(0)gamma mu(+)mu(-)
Chiral forecasting decay muon branching ratios differential branch ratio calculation
2014/12/22
We have previously analysed the chiral predictions for the decay KL ! 0 e+e− and discussed how experimental measurements of this process can help our understanding of chiral theories and of CP ...
Phenomenological issues in the determination of Delta Gamma(D)
D0 Δ Γ D experiments D0 decay model phase difference cleo
2014/12/22
We consider the issue of determining the D0– width difference ΔΓD experimentally. The current situation is reviewed and suggestions for further study are given. We propose a number of D0 decay modes i...
Decay pi(0)->gamma gamma to next to leading order in chiral perturbation theory
Decay of amplitude induced mixing pure state low energy
2014/12/20
The π0→γγ decay width is analyzed within the combined framework of chiral perturbation theory and the 1/Nc expansion up to O(p6) and O(p4×1/Nc) in the decay amplitude. The η′ is explicitly included in...
Light baryon magnetic moments and N ->Delta gamma transition in a Lorentz covariant chiral quark approach
Magnetic moment light baryons lorentz covariance baryons bound state pseudo-scalar meson
2014/12/20
We calculate magnetic moments of light baryons and N→Δγ transition characteristics using a manifestly Lorentz covariant chiral quark approach for the study of baryons as bound states of constituent qu...
A Neural Network based Background Supression Technique applied to VHE Gamma Ray Data coming from the Crab Pulsar
Imaging Atmospheric Cherenkov Technique Flux Upper Limit
2014/12/12
In this thesis we present new results for the 99.9% confidence level flux upper limits on the pulsed VHE gamma ray signal coming from the Crab pulsar. In order to achieve optimum hadronic background s...
Can Sequentially Linked Gamma-Ray Bursts Nullify Randomness?
Gamma-Ray Bursts Nullify Randomness General Physics
2012/5/17
In order to nullify the property of randomness perceived in the dispersion of gamma-ray bursts (GRB's) we introduce two new procedures. 1. Create a segmented group of sequentially linked GRB's and qua...
Elliptic gamma-function and multi-spin solutions of the Yang-Baxter equation
Elliptic gamma-function multi-spin solutions the Yang-Baxter equation
2011/7/27
Abstract: We present a generalization of the master solution to the quantum Yang-Baxter equation (obtained recently in arXiv:1006.0651) to the case of multi-component continuous spin variables taking ...
The general form of gamma-family of quantum relative entropies
gamma-family quantum relative entropies Falcone-Takesaki non-commutative flow
2011/7/27
Abstract: We use the Falcone-Takesaki non-commutative flow of weights and the resulting theory of non-commutative Lp spaces in order to define the family of relative entropy functionals that naturally...
Estimation of compact binary coalescense rates from short gamma-ray burst redshift measurements
Estimation of compact binary coalescense rates short gamma-ray redshift measurements
2010/12/21
Short gamma-ray bursts are believed to originate from the merger of two compact objects. If this scenario is correct, these bursts will be accompanied by the emission of strong gravitational waves, de...

2011/1/5
The Fermi Gamma-ray Space Telescope (Fermi) was launched on June 11, 2008 and began its
first year sky survey on August 11, 2008. The Large Area Telescope (LAT), a wide field-ofview
