Factorization and Non-factorization in Diffractive Hard Scattering
Factorization, in the sense defined for inclusive hard scattering, is
discussed for diffractive hard scattering. A factorization theorem similar to
its inclusive counterpart is presented for diffractive DIS. For hadron-hadron
diffractive hard scattering, in contrast to its inclusive counterpart, the
expected breakdown of factorization is discussed. Cross section estimates are
given from a simple field theory model for non-factorizing
double-pomeron-exchange (DPE) dijet production with and without account for
Sudakov suppression.Comment: 6 pages, Latex, DIS 97 tal
A Quantum Field Theory Warm Inflation Model
A quantum field theory warm inflation model is presented that solves the
cosmological horizon/flatness problems. An interpretation of the model is given
from supersymmetry and superstring theory.Comment: 5 pages, 0 figure, Latex, presented COSMOS-9
A Renormalization Group Approach to the Chiral Transition
A methodology is given to test the QCD =2 chiral transition, presently
conjectured to be second order. Scaling forms for the correlation length,
susceptibilities and equation of state are given which account for finite
lattice spacing. Confirmation by lattice simulation would provide a large set
of consistency checks for establishing that the transition is second order.
Further corrections from finite volume effects and higher dimensional operator
mixing are given. The implications of scaling corrections in finite temperature
lattice QCD studies are examined with emphasis on tests for the believed second
order chiral transition within the realistic setting of finite lattice spacing
effects.Comment: AZPH-TH 93-07, latex, Ann. Phys. (in press 94
