1) Email: [email protected] . 2) Email: [email protected] . 3) Email: [email protected] . In this letter we consider a new mechanism for hard inclusive production, which violates the factorization theorem [2]. We illustrate this mechanism for the case of inclusive heavy Higgs production in deutron-deutron high energy scattering. The suggested mechanism applies to any hard inclusive c...

A new mechanism for hard inclusive production, which leads to a violation of the factorization theorem, is suggested. The mechanism is illustrated by a detailed discussion of Higgs meson production in high energy deutron-deutron scattering. Numerical estimates for the effect are given for high energy hadron (nucleus) scattering. 1) Email: [email protected] . 2) Email: [email protected]...

We analyse the proton and deutron data on spin dependent asymmetry A 1 (x, Q 2) supposing the DIS structure functions g 1 (x, Q 2) and F 3 (x, Q 2) have the similar Q 2-dependence. As a result, we have obtained Γ p

The ∆-excitation in pd annihilation at rest was studied. The annihilation amplitude from the statistical model and the πN amplitude from the resonance model were adopted in our calculations. We analyze the invariant mass of the π + p and π − p systems selecting the protons with momenta above 400 MeV/c and with respect to the different final reaction channels. Our model reproduces reasonably the...

  In this project the neutron spectra from the reaction of deutron on beryllium muclei is measured. The energies of deuterons were 7, 10, 13 and 15 MeV, and these measurements are performed at 10, 30 and 50 degrees relative to the beam of deutrons. The detector used is 76 by 76 mm right circular cylender of NE-213 liquid scintillator. The zero crossing technique is used for gamma discriminatin....
