    Difference of \tilde \epsilon and \epsilon in fitting the parameters of CKM matrix

    Full text link
    The difference between induced by box diagram value of \tilde \epsilon and experimentally measured value of \epsilon is estimated. It appeared to be around 5 - 10 %, depending on the values of hadronic matrix elements. With this result, the fit of CKM marix parameters within the SM is performed.Comment: 11 pages, 1 figur

    Experimental results on fast neutron generation in D(d,n)3^{3}He and T(d,n)4^{4}He reactions in the SOKOL-P laser facility [1] are presented. Solid targets were irradiated by 1.054 μ{\rm \mu} m, s- or p-polarized laser pulses of energy 5-8 J on target and duration 0.85-2 ps. The peak laser intensity was 0.5-2 \cdot 1018^{18} W/cm2^{2}. Flat deuterated plastic (CD2)n_{2})_{\rm n} targets and Ti Dα_{\rm \alpha }Tβ_{\rm \beta} targets were used in experiments. Some experiments were carried out with additional targets placed in front of and behind the laser target. The used (TOF) time-of-flight technique helped identify neutrons from D(d,n)3^{3}He and T(d,n)4^{4}He reactions. Yields up to 106^{6 } DD-neutrons and 107^{7} DT-neutrons were measured. Interaction of the fast ion beam with the target can explain the observed yield
