Hard diffraction from parton rescattering in QCD

S. J. Brodsky, R. Enberg, P. Hoyer +1

We analyze the QCD dynamics of diffractive deep inelastic scattering. The presence of a rapidity gap between the target and diffractive system requires that the target remnant emer…

Improved description of charged Higgs boson production at hadron colliders

J. Alwall, J. Rathsman

We present a new method for matching the two twin-processes gb->H+/-t and gg->H+/-tb in Monte Carlo event generators. The matching is done by defining a double-counting term, which…

Strange quark asymmetry in the nucleon and the NuTeV anomaly

Johan Alwall, Gunnar Ingelman

The NuTeV anomaly of a non-universal value of the fundamental parameter sin^2θ_W in the electroweak theory has been interpreted as an indication for new physics beyond the Standard…

The Higgs Working Group: Summary Report 2003

K. A. Assamagan, M. Narain, A. Nikitenko +81

Theoretical progress in Higgs boson production and background processes is discussed with particular emphasis on QCD corrections at and beyond next-to-leading order as well as next…

The ATLAS discovery potential for a heavy charged Higgs boson in gg->tbH^{+-} with H^{+-}->tb

K. A. Assamagan, N. Gollub

The feasibility of detecting a heavy charged Higgs boson, m(H^{+-})>m(t)+m(b), decaying in the H^{+-}->tb channel is studied with the fast simulation of the ATLAS detector. We stud…

Interpretation of electron-proton scattering at low Q^2

Johan Alwall, Gunnar Ingelman

Low-Q^2 photons do not resolve partons in the proton, which gives problems when applying the deep inelastic scattering formalism, such as an unphysical, negative gluon density extr…
