Recent results from the DD collaboration on dijet production with rapidity gaps are discussed for center-of-mass energies of p s = 630 and 1800 GeV, including single diiractive jet production, hard double pomeron exchange, and hard color-singlet exchange.

The one-dimensional Schrr odinger equation is considered when the potential and its rst moment are absolutely integrable. The potential is uniquely constructed in terms of the scattering data consisting of the reeection coeecient from the right (left) and the knowledge of the potential on the right (left) half line of the real axis. Hence, neither the bound state energies nor the bound state no...

We propose a model of inflation based on a simple variant of the NMSSM, called φNMSSM where the additional singlet φ plays the role of the inflaton in hybrid (or inverted hybrid) type models. The φNMSSM solves the μ problem of the MSSM via the vacuum expectation value of the gauge singlet N, but also solves the strong CP problem through an approximate Peccei-Quinn symmetry. The potential energy...

Abstract: In this paper solid state reduction of high carbon ferrochromium-chromite composite pellets in the temperature range of 900-1350°C was investigated. A two stage reduction mechanism is proposed. The first stage is likely to be controlled by the chemical reaction with activation energy of 127.2kJ/mol. In the second stage, solid state diffusion of carbon through the reaction product ...

New high-resolution visible emission spectra of the MgH molecule have been recorded with high signal-to-noise ratios using a Fourier transform spectrometer. Many bands of the A 2Pi-->X 2Sigma+ and B' 2Sigma+-->X 2Sigma+ electronic transitions of 24MgH were analyzed; the new data span the v' = 0-3 levels of the A 2Pi and B'2Sigma+ excited states and the v''=0-11 levels of the X 2Sigma+ ground el...

We study the evolution of heavy quarkonium states with temperature in a Quark-Gluon Plasma by evaluating an in-medium Q ¯ Q T −matrix within a reduced Bethe-Salpeter equation in S− and P −wave channels. The interaction kernel is extracted from finite-temperature QCD lattice calculations of the singlet free energy of a Q ¯ Q pair. Quarkonium bound states are found to gradually move across the Q ...

The phase diagram of the unconventional superconductor UPt3 is explained under the long-standing hypothesis that the pair wavefunction belongs to the E1g representation of the point group. The main objection to this theory has been that it disagrees with the experimental phase diagram when a field is applied along the c-axis. By a careful analysis of the free energy this objection is shown to b...

following our previous presentation of a new three-fold symmetry for derivation of the magic numbers of nuclei based upon a quark state model of nuclei, here the nuclear binding energy is obtained from such new perspective. from this point of view, since each nucleon is made of three quarks, the binding energy of nuclei contains a volume term proportional to 3a (a is mass number). by considerin...
