Associated heavy quarks pair production with Higgs as a tool for a search for non-perturbative effects of the electroweak interaction at the LHC
Assuming an existence of an anomalous triple electro-weak bosons interaction
being defined by coupling constant , we calculate its contribution to
interactions of the Higgs with pairs of heavy particles. Bearing in mind
experimental restrictions we present results for
possible effects in processes , . Effects could be
significant with negative sign of in associated heavy quarks
pairs production with the Higgs. In calculations we rely on results of the
non-perturbative approach to a spontaneous generation of effective
interactions, which defines the form-factor of the three-boson anomalous
interaction.Comment: 6 pages, 2 figures, few typos corrected, references adde
Energy dependence of current noise in superconducting/normal metal junctions
Interference of electronic waves undergoing Andreev reflection in diffusive
conductors determines the energy profile of the conductance on the scale of the
Thouless energy. A similar dependence exists in the current noise, but its
behavior is known only in few limiting cases. We consider a metallic diffusive
wire connected to a superconducting reservoir through an interface
characterized by an arbitrary distribution of channel transparencies. Within
the quasiclassical theory for current fluctuations we provide a general
expression for the energy dependence of the current noise.Comment: 5 pages, 1 Figur
A Discrete Version of the Inverse Scattering Problem and the J-matrix Method
The problem of the Hamiltonian matrix in the oscillator and Laguerre basis
construction from the S-matrix is treated in the context of the algebraic
analogue of the Marchenko method.Comment: 11 pages. The Laguerre basis case is adde
