Abstract:

We present a search for neutral supersymmetric Higgs bosons decaying to τ pairs produced in pp̄ collisions at s=1.96TeV. The data, corresponding to 310pb-1 integrated luminosity, were collected with the Collider Detector at Fermilab in runII of the Tevatron. No significant excess above the standard model backgrounds is observed. We set exclusion limits on the production cross section times branching fraction to τ pairs for Higgs boson masses in the range from 90 to 250GeV/c2. © 2006 The American Physical Society.

Abstract:

We present a search for the standard model Higgs boson in H→WW(*) decays with e+e-, e±μ, and μ+μ- final states in pp̄ collisions at a center-of-mass energy of s=1.96TeV. The data, collected from April 2002 to June 2004 with the D0 detector, correspond to an integrated luminosity of 300-325pb-1, depending on the final state. The number of events observed is consistent with the expectation from backgrounds. Limits from the combination of all three channels on the Higgs boson production cross section times branching ratio σ×BR(H→WW(*)) are presented. © 2006 The American Physical Society.

Impact of future HERA data on the determination of proton parton distribution functions using the ZEUS NLO QCD fit

Journal of Physics G Institute of Physics 32:2 (2006) 221

Authors:

Claire Gwenlan, Amanda M Cooper-Sarkar, Christopher Targett-Adams

Abstract:

The high precision and large kinematic coverage of the data from the HERA-I running period (1994-2000) have already allowed precise extractions of proton parton distribution functions. The HERA-II running program is now underway and is expected to provide a substantial increase in the luminosity collected at HERA. In this paper, a study is presented which investigates the potential impact of future data from HERA on the proton PDF uncertainties, within the currently planned running scenario. Next-to-leading order QCD predictions for inclusive jet cross sections at the LHC centre-of-mass energy are presented using the estimated PDFs. Finally, the effect of a possible future measurement of the longitudinal structure function, FL, on the gluon distribution is investigated.

Impact of future HERA data on the proton PDF uncertainties using the ZEUS NLO QCD fit

Journal of Physics G: Nuclear and Particle Physics IOP Publishing 32:2 (2006) 221-228

Authors:

Claire Gwenlan, A Cooper-Sarkar, C Targett-Adams

Abstract:

The high precision and large kinematic coverage of the data from the HERA-I running period (1994-2000) have already allowed precise extractions of proton parton distribution functions. The HERA-II program is now underway and is expected to provide a substantial increase in the luminosity collected at HERA. In this paper, the first estimate of the impact of future data from HERA, on the proton PDF uncertainties, is presented. Next-to-leading order QCD predictions for inclusive jet cross sections at the LHC are presented using the projected PDFs.
