The MSSM is extended to the $U(1)_X$SSM, whose local gauge group $SU(3)_C \times SU(2)_L U(1)_Y U(1)_X$. To obtain we add new superfields MSSM, namely: three Higgs singlets $\hat{\eta},~\hat{\bar{\eta}},~\hat{S}$ and right-handed neutrinos $\hat{\nu}_i$. It can give light neutrino tiny mass at tree level through seesaw mechanism. study of contribution two-loop diagrams MDM muon under $U(1)_X$SS...

Two-loop HQET propagator diagrams were reduced [1] to two master integrals, using integration by parts [2] identities. There are 10 generic topologies of three-loop HQET propagator diagrams (Fig. 1). They can be reduced [3], using integration by parts relations, to 8 master integrals (Fig. 2). The algorithm has been constructed by hand, and implemented as a REDUCE package Grinder [3]. It is ana...

A structural model of LiPON solid electrolyte, containing elements that simulate drift conductivity, diffusion and leakage current was proposed. The dependence the impedance on frequency calculated, parameters at which theoretical curve best approximates experimental Nyquist diagrams were determined. Based these data, ion coefficient conductivity are D1 = 1.5 × 10−11 cm2/s σ 1.9 10−6 S/cm, resp...

fe49co33ni18 nanowire arrays (175 nm in diameter and lengths ranging from 5 to 32μm) were fabricated into nanopores of hard-anodized aluminum oxide templates using pulsed ac electrodeposition technique. hysteresis loop measurements indicated that increasing the length decreases coercivity and squareness values (from 274 oe and 0.58 to200 oe and 0.105, respectively), indicating the increase in m...
