The twist-four quark and gluon distributions in a transversely polarized nucleon are identified and relations among them are discussed by using QCD equations of motion. Their contribution, at the order of O ( 1/Q ) , to the Drell-Yan cross section in transversely polarized nucleon-nucleon collisions is calculated. Submitted to: Phys. Rev.

We study the duality of N = 1 gauge theories in the presence of a massless adjoint field. We calculate the superpotential using the factorization method and compare with the result obtained by applying Kutasov duality. The latter result is just the leading term of the former, indicating that Kutasov duality is exact only in the IR limit as claimed in the original literature. We also study vario...

In a decade-long soil warming experiment in a mid-latitude hardwood forest, we documented changes in soil carbon and nitrogen cycling in order to investigate the consequences of these changes for the climate system. Here we show that whereas soil warming accelerates soil organic matter decay and carbon dioxide fluxes to the atmosphere, this response is small and short-lived for a mid-latitude f...

As everybody in this audience knows, there are (at least) two important and exciting progress in particle physics in recent years. The first one is of course ∗Invited plenary talk given at 3rd International Workshop on Physics and Experiments with e+e− Linear Colliders, 8-12 Sep 1995 , Iwate, Japan †This work was supported in part by the Director, Office of Energy Research, Office of High Energ...

There is evidence for substantial nonperturbative effects in the structure functions extracted from deep-inelastic lepton-nucleon scattering. These effects have a major impact on us and A determinations. Results which I reported previously for pN and vN scattering (Fz and xF3) are extended to include ed data which are at lower W2 and higher x and have extremely high statistics. Possible analyti...

Soft-collinear effective theory is generalized to include soft massless quarks in addition to collinear fields. This extension is necessary for the treatment of interactions with the soft spectator quark in a heavy meson. The power counting of the relevant fields and the construction of the effective Lagrangian are discussed at leading order in Λ/mb. Several novel effects occur in the matching ...

We study the Hawking radiation for the geometry of an evaporating 1+1 dimensional black hole. We compute Bogoliubov coefficients and the stress tensor. We use a recent result of Srednicki to estimate the entropy of entanglement produced in the evaporation process, for the 1+1 dimensional hole and for the 3+1 dimensional hole. It is found that the one space dimensional result of Srednicki is the...

We consider the one-dimensional random field Ising model, where the spin-spin coupling, J , is ferromagnetic and the external field is chosen to be +h with probability p and −h with probability 1− p. At zero temperature, we calculate an exact expression for the correlation length of the quenched average of the correlation function 〈s0sn〉 − 〈s0〉 〈sn〉 in the case that 2J/h is not an integer. The ...
