Searches for Dijet Resonances
Author: Lydia Audrey Beresford
Publisher: Springer
ISBN: 331997520X
Category : Science
Languages : en
Pages : 175
Book Description
This book addresses one of the most intriguing mysteries of our universe: the nature of dark matter. The results presented here mark a significant and substantial contribution to the search for new physics, in particular for new particles that couple to dark matter. The first analysis presented is a search for heavy new particles that decay into pairs of hadronic jets (dijets). This pioneering analysis explores unprecedented dijet invariant masses, reaching nearly 7 TeV, and sets constraints on several important new physics models. The two subsequent analyses focus on the difficult low dijet mass region, down to 200 GeV, and employ a novel technique to efficiently gather low-mass dijet events. The results of these analyses transcend the long-standing constraints on dark matter mediator particles set by several existing experiments.

First Observation of Dijet Events with an Antiproton Tag at Center of Mass Energy
Author: Michael Allen Strang

Category : Physics

Pages :
Book Description
The Forward Proton Detector (FPD) is a new sub-system of the DO detector, a 5000 ton particle physics detector located at the Fermilab Tevatron proton-antiproton collider. The FPD was implemented for the Tevatron Run II and gives access to a wide range of diffractive scattering processes, where one or both of the beam particles remain intact. The analysis described in this thesis makes use of the dipole spectrometer of the FPD to tag outgoing antiprotons in events that have a dijet signature in the central DO calorimeter. Properties of jets with a diffractive tag signature are compared to jets without such a signature yielding the first observation of tagged diffractive dijets at a 1.96 TeV center-of-mass energy.

Book Description
The authors report a measurement of the diffractive structure function of the antiproton for dijet events produced in association with a leading antiproton in {anti p}p collisions at (square root)(s) = 1800 GeV. Comparing their results with expectations based on parton densities extracted by the H1 Collaboration from diffractive deep inelastic scattering at the DESY ep collider HERA, the authors find a severe breakdown of QCD factorization.
