γ-preinvexity and γ-invexity in mathematical programming

γ - γ Coincidence in 22

Na radioactively decays to an excited state of Ne either by emission of a positron (90% probability) or by electron capture (10% probability). The excited Ne nucleus decays with a mean life 3×10−12 s to the ground state with the emission of a 1.274 MeV gamma. The positrons are emitted with a range of kinetic energies up to about 0.5 MeV. They lose this energy quickly (10−9 s) in the material !"...

Precise measurement of Γ ( K → eν ( γ ) ) / Γ ( K → μ ν ( γ ) ) and study of K →

We present a precise measurement of the ratio RK = Γ(K → eν(γ))/Γ(K → μν(γ)) and a study of the radiative process K → eνγ, performed with the KLOE detector. The results are based on data collected at the Frascati ee collider DAΦNE for an integrated luminosity of 2.2 fb. We find RK = (2.493 ± 0.025stat ± 0.019syst) × 10 , in agreement with the Standard Model expectation. This result is used to i...

Measurement of γ and 2 β + γ

We report on the initial measurements of the angle γ and the sum of angles 2β + γ of the Unitarity Triangle. When compared with indirect information on the value of γ from other measurements of CKM parameters, the measurement of these angles will provide a precise test of Standard Model predictions, as statistics increase. There are several methods for directly measuring γ and 2β + γ. We report...

QCD Saturation and γ∗-γ∗ Scattering

Two photon collisions at high energy have an important theoretical advantage: the simplicity of the initial state, which gives us a unique opportunity to calculate these processes for large virtualities of both photons in perturbative QCD approach. In this paper we study QCD saturation in two photon collisions in the framework of the Glauber-Mueller approach. The Glauber-Mueller formula is deri...
