The Gluon Green's function in N=4 supersymmetric YangMills theory.
Andersen, Jeppe R.; Sabio Vera, Agustin (HEP, Cavendish Laboratory, University of Cambridge, 200406)The high energy limit of scattering amplitudes in the N = 4 supersymmetric Yang– Mills theory is studied by solving the corresponding BFKL equation in the next– to–leading approximation. The gluon Green’s function is ... 
The Gluon Green's function in the BFKL approach at nexttoleading logarithmic accuracy.
Andersen, Jeppe R.; Sabio Vera, Agustin (HEP, Cavendish Laboratory, University of Cambridge, 200309)We investigate the gluon Green’s function in the high energy limit of QCD using a recently proposed iterative solution of the Balitsky–Fadin–Kuraev–Lipatov (BFKL) equation at next–to–leading logarithmic (NLL) accuracy. ... 
Inclusive double diffractive production of SUSY particles at the LHC.
Bursa, Francis; Sabio Vera, Agustin (HEP, Cavendish Laboratory, University of Cambridge, 200309)We estimate the inclusive double diffractive production of SUSY particles at the LHC using a modified version of the POMWIG Monte Carlo event generator. The diffractive events are produced via the Ingelman–Schlein model ... 
Mass bounds in a model with a triplet Higgs.
Forshaw, Jeffrey R.; Sabio Vera, Agustin; White, B. E. (HEP, Cavendish Laboratory, University of Cambridge, 200302)We perform an analysis of the Renormalization Group evolution of the couplings in an extension to the Standard Model which contains a real triplet in the Higgs sector. Insisting that the model remain valid up to 1 TeV ... 
Phenomenology of a SU(2) triplet Higgs.
Sabio Vera, Agustin (HEP, Cavendish Laboratory, University of Cambridge, 200307)We study the Renormalization Group (RG) evolution of the couplings in a model with a real SU(2) triplet in the Higgs sector. Insisting that the model remain valid up to 1 TeV we show that it is possible for there to be ... 
Solution of the BFKL equation at nexttoleading order.
Sabio Vera, Agustin (HEP, Cavendish Laboratory, University of Cambridge, 200307)We solve the Balitsky–Fadin–Kuraev–Lipatov (BFKL) equation in the next–to–leading logarithmic approximation for forward scattering with all conformal spins using an iterative method . 
Solving the BFKL equation in the nexttoleading approximation.
Andersen, Jeppe R.; Sabio Vera, Agustin (HEP, Cavendish Laboratory, University of Cambridge, 200305)The Balitsky–Fadin–Kuraev–Lipatov equation in the next–to–leading logarithmic approximation is solved using an iterative method. We derive the solution for forward scattering with all conformal spins. A discussion of the ... 
A Study of the gluon ladder in diffractive processes.
Andersen, Jeppe R.; Sabio Vera, Agustin (HEP, Cavendish Laboratory, University of Cambridge, 200411)The solution to the non–forward BFKL equation in the Leading Logarithmic approximation is expressed in terms of a sum of iterations of its kernel directly in transverse momentum and rapidity space. Several studies of the ... 
W Boson production at large transverse momentum.
Kidonakis, Nikolaos; Sabio Vera, Agustin (HEP, Cavendish Laboratory, University of Cambridge, 200405)The production of W bosons at large transverse momentum in p¯p collisions is studied. The nexttoleading order cross section in this region is dominated by threshold softgluon corrections. The transverse momentum ... 
W hadroproduction at large transverse momentum beyond nexttoleading order.
Kidonakis, Nikolaos; Sabio Vera, Agustin (HEP, Cavendish Laboratory, University of Cambridge, 200311)We study the production of W bosons at large transverse momentum in p¯p collisions. We show that the nexttoleading order cross section at large transverse momentum is dominated by threshold softgluon corrections. We ...
