The ν-ball γ-spectrometer

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...

Effect of CaO on the Formation of PSZ and γ-Zirconia Nanoparticles through Ball Milling

The effect of CaO on the formation of β- and γ-zirconia nanoparticles from α-zirconia was investigated and their stability evaluated via mechanical activation. α-ZrO2+8.5wt%CaO powder was milled for 2-150 hours with ball-to-powder weight ratios (BPWR) of 40:1 and 60:1. Structural evaluations were conducted using X-Ray diffraction and scanning electron microscope (SEM). Thermal analysis wa...

Electromagnetic catalysis of the radiative transitions of ν i → ν j γ type in the field of an intense monochromatic wave

Electromagnetic catalysis of the radiative transitions of ν i → ν j γ type in the field of an intense monochromatic wave Abstract The radiative decay of the massive neutrino ν i → ν j γ in a circularly polarized electromagnetic wave is investigated within the Standard theory with lepton mixing. The decay probability in the wave field does not contain a threshold factor ∼ (1 − m i /m j) as oppos...
