The reaction e + e − → e + e − γ ∗ γ ∗ → e + e − hadrons for quasi-real photons is studied using data from s =183 GeV up to 202 GeV. Results on the total cross sections σ( e + e − → e + e − hadrons ) ...

Four-point correlation functions are calculated for the basic operators in 2D conformal invariant theories with the central charge of the corresponding Virasoro algebra C ≤1. Based on these results, ...

Fission cross section ratios of 233U, 238U, 232Th, 239Pu, 237Np, natural Pb and 209Bi to 235U have been measured in a wide energy range of incident neutrons from 1 MeV to 200 MeV using a ...

Using the data on deep inelastic muon scattering on iron and deuterium the ratio of the nucleon structure functions F 2 N ( Fe )/ F 2 N ( D ) is presented. The observed x -dependence of this ratio is ...

The requirement that P and T be approximately conserved in the color gauge theory of strong interactions without arbitrary adjustment of parameters is analyzed. Several possibilities are identified, ...

We propose new mechanisms for understanding neutrino masses in superstring models that contain E6-singlet zero-mass fields after compactification. We show that the low-energy gauge group of these ...

The 17O(p,γ)18F reaction plays an important role in hydrogen-burning nucleosynthesis. Conflicting values for the low-energy behavior of its cross section exist in the literature. We present direct ...

Formulae for the line-of-sight and transverse comoving distances, proper motion distance, angular diameter distance, luminosity distance, k-correction, distance modulus, comoving volume, lookback time ...

The production of a top quark-antiquark pair in association with the recentlydiscovered Standard Model Higgs boson (t¯tH) provides a promising avenue to search for new physics, due to the large mass ...
