Diffractive Hard Scattering with a Coherent Pomeron

John C. Collins, Leonid Frankfurt, Mark Strikman

Diffractive scattering involves exchange of a Pomeron to make a rapidity gap. It is normally assumed that to get a hard scattering in diffraction, one may treat the Pomeron as an o…

Finite left-distributive algebras and embedding algebras\endtitle

Randall Dougherty, Thomas Jech

We consider algebras with one binary operation and one generator ({\it monogenic}) and satisfying the left distributive law .…

Spin-Spin Asymmetries in Large Transverse Momentum Higgs Boson Production

M. A. Doncheski, R. W. Robinett, L. Weinkauf

We examine the spin-dependence of standard model Higgs boson production at large transverse momentum via the processes , , and $q\overline…

Breakdown of Dimensional Regularization in the Sudakov Problem

J. C. Collins, F. V. Tkachov

An explicit example is presented (a one-loop triangle graph) where dimensional regularization fails to regulate the infra-red singularities that emerge at intermediate steps of stu…

Fragmentation of Transversely Polarized Quarks Probed in Transverse Momentum Distributions

John Collins

It is shown that the azimuthal dependence of the distribution of hadrons in a quark jet is a probe of the transverse spin of the quark initiating the jet. This results in a new spi…

Hard Scattering in QCD with Polarized Beams

John C. Collins

I show that factorization for hard processes in QCD is also valid when the detected particles are polarized, and that the proof of the theorem determines the operator form for the…

Loop Variables and the Virasoro Group

B. Sathiapalan

We derive an expression in closed form for the action of a finite element of the Virasoro Group on generalized vertex operators. This complements earlier results giving an algorith…

On the Chiral Rings in N=2 and N=4 Superconformal Algebras

Murat Gunaydin

We study the chiral rings in N=2 and N=4 superconformal algebras. The chiral primary states of N=2 superconformal algebras realized over hermitian triple systems are given. Their c…

A Short Proof of Jacobi's Formula for the Number of Representations of an Integer as a Sum of Four Squares

George Andrews, Shalsoh B. Ekhad, Doron Zeilberger

A short and elementary proof, and a finite-form generalization, are given of Jacobi's formula for the number of ways of writing an integer as a sum of four squares (that implies La…

On Gödel's second incompleteness theorem

Thomas Jech

A very short proof of Gödel's second incompleteness theorem (for set theory, second order arithmetic etc.)

A note on canonical functions

Thomas Jech, Saharon Shelah

We construct a generic extension in which the aleph_2 nd canonical function on aleph_1 exists.
