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 ...

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 ...

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, ...

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 ...

We have searched for the lepton-flavor-violating decay D0→e±μ∓ in 204 pb−1 of e+e− annihilation data at Ec.m.=29 GeV from the Mark II detector. No candidates were found; we estimate an upper limit on ...

Supersymmetry is a remarkable subject that has fascinated particle physicists since it was originally introduced. Although supersymmetry is no longer a new idea, we still do not know in what form, if ...
