Production of. gamma. (9. 5) in e/sup +/e/sup -/ annihilation and photoproduction. [Cross sections]

Description: Assuming that the new resonance ..gamma..(9.5) is a vector meson, its leptonic and hadronic decay widths are calculated in analogy to those of psi(3.1). Then, using the Breit-Wigner formula, the production cross section in e/sup +/e/sup -/ annihilation is predicted. The tensor dominance of the Pomeron, together with the vector dominance model, is invoked to estimate the photoproduction cross section.

Fermion masses and neutrino mixing in an SU(5)/sub GUT/ x SU(8)/sub ETC/ model

Description: We extend the SU(3) x SU(2) x U(1) model without scalars to SU(5)/sub GUT/ x SU(8)/sub ETC/. In our model, the mixing in the leptons is identical to that for the quarks, so that the Cabibbo angle determines the mixing of nu/sub e/ and nu/sub ..mu../. The quark masses and mixing angles are studied for two and three generations of quarks.

Inclusive neutrino interactions in a six quark model

Description: The effects of non-diagonal terms in the neutral current of an SU(2) x U(1) gauge six-quark model with slow rescaling are examined. The model reproduces the experimental charged current data with appropriate choice of heavy quark masses. The experimental neutral current data requires at least five quarks to explain it. In our context, the predictions for various heavy quark masses and quark mixings differ most for energies in the range 0 to 50 GeV. The various quantities are also calculated for… more

Phenomenological bounds in inclusive neutrino interactions

Description: Using expressions for the $nu$ and anti $nu$ charged and neutral current cross sections and the electroproduction structure function integral and positivity requirements of the sea contribution, bounds are obtained on sigma/sup anti nu N//sigma/sup anti nu N/, and sigma/sup anti nu N//sub nc//sigma/sup nu N/ /sub nc/ in the standard model. A bound on sigma/sup anti nu N//sigma/sup nu N/ obtained with a V + A term anti p'$gamma$/sub mu/(1-$gamma$$sub 5$)n is used to rule out such a term in the c… more

Resonant production of high-transverse-momentum back-to-back gluon jets in pp collisions. [27 GeV, cross sections, transverse momentum, angular distribution, proposed experiment]

Description: The calorimetric study of two-gluon jets arising from inclusive production of 0/sup - +/, 0/sup + +/, and 2/sup + +/ b anti b states in hadron--hadron collisions was proposed. Cross sections of approx. = 0.2 x 10/sup -33/ cm/sup 2/ (approx. = 3 x 10/sup -33/ cm/sup 2/) are predicted for pp collisions at ..sqrt..s = 27 GeV (60 GeV). Also calculated were the transverse momentum and angular distributions of the jets. 14 references.

Baryon--antibaryon pair decay of eta/sub c/ in coherent production. [Cross sections, angular distribution]

Description: The feasibility of observing eta/sub c/ by its OZI-rule-forbidden baryon-antibaryon pair decay in the coherent production (Primakoff effect) of eta/sub c/ is investigated. The cross sections are estimated as a function of photon energy, and the CM angular distribution is calculated.
