The results of the MACRO experiment on atmospheric neutrino oscillations are presented and discussed. The data concern different event topologies with average neutrino energies of ∼ 4 and ∼ 50 GeV. The Multiple Coulomb Scattering of muons in the MACRO absorbers was used to estimate the neutrino energy of each event of the higher energy sample. The angular distributions, the absolute fluxes and ...

A simple algorithm is presented for evaluating scattering parameters of a two-port network. This technique uses the indefinite admittance matrix to calculate scattering or any other desired set of two-port parameters.

Realistic nuclear structure calculations are presented for the event rates due to coherent elastic neutrino-nucleus scattering (CEνNS), assuming neutrinos from pion-decay at-rest, reactors and Earth’s interior. We focus on currently interesting Germanium isotopes, 70,73,76Ge, which constitute detector materials of recently planned CEνNS experiments. study in addition potential use 64,70Zn 28Si ...

Ion ejection from charged helium nanodroplets exposed to intense femtosecond soft X-ray pulses is studied by single-pulse ion time-of-flight (TOF) spectroscopy in coincidence with small-angle scattering. Scattering images encode the droplet size and absolute photon flux incident on each droplet, while TOF spectra are used determine maximum kinetic energy, $$E_{\text {kin}}$$ , of $$\hbox {He}_{...

In this paper, we construct a conformal scattering theory for Dirac fields in the interior of Reissner–Nordström-like black hole, between hole event horizon and Cauchy horizon. The main result is resolution characteristic problem equation on horizons by solving system wave equations re-interpreting its solution as components required solution.

this paper measures event risk which is introducing by the ball committee to measure the effect of sudden news. this study calculates event risk by using the data of registered firms in tehran stock market between 1993 and 1994. for computing event risk, we use daily market capitalization for 80 firms during 1993-2009, then dividing these firms to three baskets; big, medium and small. the model...
