Search for Diphoton Events with Large Missing Transverse Energy in proton-antiproton collisions at sqrt(s) = 1.8 TeV
S. Abachi
A search for signals of new physics has been carried out in the channel p pbar -> gamma gamma + ETmiss. This signature is expected in various recently proposed supersymmetric (SUSY…
Search for Top Squark Pair Production in the Dielectron Channel
D0 Collaboration, S. Abachi
This report describes the first search for top squark pair production in the channel stop_1 stopbar_1 -> b bbar chargino_1 chargino_1 -> ee+jets+MEt using 74.9 +- 8.9 pb^-1 of data…
Limits on Anomalous Couplings from Events at TeV
The DZero Collaboration, S. Abachi
We have measured the gauge boson coupling parameters using () events at TeV. The data, corresponding to an integrated luminosi…
Charge Localization in Disordered Colossal-Magnetoresistance Manganites
Qiming Li, Jun Zang, A. R. Bishop +1
The metallic or insulating nature of the paramagnetic phase of the colossal-magnetoresistance manganites is investigated via a double exchange Hamiltonian with diagonal disorder. M…
Effective Regge QCD
Victor T. Kim, Grigorii B. Pivovarov
A new framework for a high energy limit of quantum gauge field theories is introduced. Its potency is illustrated on a new derivation of the reggeization of the gluon.
Isolated Prompt Photon Cross Sections
Edmond L. Berger, Xiaofeng Guo, Jianwei Qiu
We show that the conventionally defined partonic cross section for the production of isolated prompt photons is not an infrared safe quantity. We work out the case of $e^+e^-\toγ+…
