Resummation of thrust distributions in DIS
Vito Antonelli, Mrinal Dasgupta, Gavin P. Salam
We calculate the resummed distributions for the thrust in DIS in the limit T->1. Two variants of the thrust are considered: that normalised to Q/2, and that normalised to the energ…
HERWIG 6.1 Release Note
G. Corcella, I. G. Knowles, G. Marchesini +5
A new version of the Monte Carlo program HERWIG (version 6.1) is now available. This note gives brief details of the new features relative to the previous version (5.9). A fully up…
Universality of 1/Q corrections revisited
Mrinal Dasgupta, Lorenzo Magnea, Graham Smye
We provide an exact analytical calculation at the two-loop level in the abelian limit of the leading power correction for the C parameter in e+e- annihilation. We compare our resul…
Power corrections to the differential Drell-Yan cross section
Mrinal Dasgupta
We estimate the power corrections (infrared renormalon contributions) to the coefficient functions for the differential Drell-Yan cross-section , where is the ma…
The resummed thrust distribution in DIS
V. Antonelli, M. Dasgupta, G. P. Salam
We present preliminary results on the resummation of leading and next-to-leading logarithms for the thrust distribution in deep inelastic scattering. Our predictions, expanded to O…
Power corrections and the interplay between perturbative and non-perturbative phenomena
G. P. Salam, G. Zanderighi
We discuss the issue of interplay between perturbative and non-perturbative phenomena for power corrections to e+e- event shapes.
Initial State Radiation in Simulations of Vector Boson Production at Hadron Colliders
Gennaro Corcella, Michael H. Seymour
The production of vector bosons at present and future hadron colliders will provide a crucial test for QCD and Standard Model physics. In this paper we improve parton shower simula…
A collinear model for small-x physics
M. Ciafaloni, D. Colferai, G. P. Salam
We propose a simple model for studying small-x physics in which we take only the collinearly enhanced part of leading and subleading kernels, for all possible transverse momentum o…
A 3-Dimensional Calculation of Atmospheric Neutrino Flux
G. Battistoni, A. Ferrari, P. Lipari +3
An extensive 3-dimensional Monte Carlo calculation of the atmospheric neutrino flux is in progress with the FLUKA Monte Carlo code. The results are compared to those obtained under…
Angular Dependence of the Radiative Gluon Spectrum and the Energy Loss of Hard Jets in QCD Media
R. Baier, Yu. L. Dokshitzer, A. H. Mueller +1
The induced momentum spectrum of soft gluons radiated from a high energy quark propagating through a QCD medium is derived in the BDMPS formalism. A calorimetric measurement for th…
1/Q^2 corrections in DIS fragmentation functions
M. Dasgupta, G. E. Smye
We present results of recent calculations of power corrections to single-hadron inclusive momentum distributions in the current hemisphere of the Breit frame in DIS. Though results…
Renormalization Group Improved Small-x Equation
M. Ciafaloni, D. Colferai, G. P. Salam
We propose and analyze an improved small-x equation which incorporates exact leading and next-to-leading BFKL kernels on one hand and renormalization group constraints in the relev…
Non-perturbative effects in the energy-energy correlation
Yu. L. Dokshitzer, G. Marchesini, B. R. Webber
The fully resummed next-to-leading-order perturbative calculation of the energy-energy correlation in annihilation is extended to include the leading non-perturbative powe…
BFKL and CCFM final states
G. P. Salam
I give a brief presentation of recent results on the equivalence of BFKL and CCFM small-x final states, and discuss their implications for phenomenology.
Radiative large-angle Bhabha scattering in collinear kinematics
V. Antonelli, E. A. Kuraev, B. G. Shaikhatdenov
The process of large-angle high energy electron-positron scattering with emission of one hard photon almost collinear to one of the charged particles momenta is considered. The dif…
A Phenomenological Study of Heavy-Quark Fragmentation Functions in e+e- Annihilation
P. Nason, C. Oleari
We consider the computation of D and B fragmentation functions in e+e- annihilation. We compare the results of fitting present data using the next-to-leading-logarithmic resummed a…
Sudakov Resummation Effects in Prompt-Photon Hadroproduction
S. Catani, M. L. Mangano, P. Nason +2
We compute the effects of soft-gluon resummation, at the next-to-leading-logarithmic level, in the fixed-target hadroproduction cross section for prompt photons. We find in general…
BS and DS equations in a Wilson loop context in QCD, effective mass operator, q-qbar spectrum
M. Baldicchi, G. M. Prosperi
We briefly discuss the quark-antiquark Bethe-Salpeter equation and the quark Dyson-Schwinger equation derived in preceding papers. We also consider the q-qbar quadratic mass operat…
A Note on W Production at HERA
P. Nason, R. Rueckl, M. Spira
We discuss W boson production at HERA including NLO QCD corrections.
Soft emissions and the equivalence of BFKL and CCFM final states
G. P. Salam
This article demonstrates that the BFKL and CCFM equations, despite their different physical content, lead to equivalent results for any final-state observable at leading single-lo…
A real CKM matrix?
P. Checchia, E. Piotto, F. Simonetto
The hypothesis of a real Cabibbo-Kobayashi-Maskawa matrix has been considered and found to be disfavoured by present measurements even when neglecting results from CP violation in…
