Soft-gluon resummation and NNLO corrections for direct photon production
Nikolaos Kidonakis, J. F. Owens
The resummation of threshold logarithms for direct photon production cross sections in hadronic collisions is presented. The resummation is based on the factorization properties of…
Large-x Parton Distributions
S. Kuhlmann, J. Huston, J. Morfin +5
Reliable knowledge of parton distributions at large x is crucial for many searches for new physics signals in the next generation of collider experiments. Although these are genera…
Calculable Sparticle Masses with Radiatively Driven Inverted Mass Hierarchy
Howard Baer, Pedro Mercadante, Xerxes Tata
Supersymmetric models with an inverted mass hierarchy (IMH: multi-TeV first and second generation matter scalars, and sub-TeV third generation scalars) can ameliorate problems aris…
1/m_Q Corrections to the Bethe-Salpeter Equation for Λ_{Q} in the Diquark Picture
X. -H. Guo, A. W. Thomas, A. G. Williams
Corrections of order 1/m_Q (Q=b or c) to the Bethe-Salpeter (B-S) equation for Λ_Q are analyzed on the assumption that the heavy baryon Λ_Q is composed of a heavy quark and a scala…
Electroweak-boson hadroproduction at large transverse momentum: factorization, resummation, and NNLO corrections
Nikolaos Kidonakis, Vittorio Del Duca
We study the resummation of singular distributions for electroweak-boson production at large transverse momentum in hadronic collisions. We describe the factorization properties of…
Stop Decays with R-Parity Violation and the Neutrino Mass
Marco Aurelio Diaz
The atmospheric and solar neutrino problems can be explained in a supersymmetric scenario where R-parity is broken bilinearly. Within this context we explore the decays of the top…
Measuring the Higgs Yukawa Couplings at a Next Linear Collider
S. Dawson, L. Reina
We investigate the inclusive production of a Higgs boson with a pair of heavy quarks (t-tbar b-bbar), in e^+e^- collisions at high energies, sqrt(s)=500 GeV and sqrt(s)=1 TeV. We c…
Gauge and Yukawa Unification in SUSY with Bilinearly Broken R-Parity
Marco Aurelio Diaz
In a supersymmetric model where R-Parity and lepton number are violated bilinearly in the superpotential, which can explain the solar and atmospheric neutrino problems, we study th…

Marco A. Diaz, Javier Ferrandis, Jose W. F. Valle
We study the predictions for M_top, tan(beta) and V_cb in a popular texture ansatze for the fermion mass matrices. We do this both for the Minimal Supersymmetric Standard Model (MS…
Two-Body Decays of the Lightest Stop in Supergravity with and without R-Parity
Marco A. Diaz, Diego A. Restrepo, Jose W. F. Valle
We study the decays of the lightest top squark in supergravity models with and without R-parity. Using the simplest model with an effective explicit bilinear breaking of R-parity a…

The simplest unified extension of the Minimal Supersymmetric Standard Model with bi-linear R--Parity violation provides a predictive scheme for neutrino masses which can account fo…

Unification of gauge couplings and the tau neutrino mass in Supergravity without R-parity
M. A. Diaz, J. Ferrandis, J. C. Romao +1
Minimal R-parity violating supergravity predicts a value for smaller than in the case with conserved R-parity, and therefore closer to the experimental world average…

Gianluca Oderda, Nikolaos Kidonakis, George Sterman
We review some techniques of resummation applied to heavy quark production in hadronic scattering and electroproduction near partonic threshold, and discuss the reduction of factor…
Trilepton Signal for Supersymmetry at the Fermilab Tevatron Revisited
Howard Baer, Manuel Drees, Frank Paige +2
Within a wide class of models, the LEP2 lower limit of 95 GeV on the chargino mass implies gluinos are heavier than 300 GeV. In this case electroweak $\tw_1\twb_1$ and $\tw_1…
