IFT 94/23 TESTING THE WWγ COUPLING AT e + e − COLLIDERS ∗
The production of single photons plus missing energy at future ee colliders can provide a testing ground for non-standard WWγ couplings. We show that even with conservative estimates of systematic errors there is still considerable sensitivity to anomalous couplings. In spite of many experimental successes certain aspects of the standard model still await for direct tests. Among them is the non...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولthe effect of using model essays on the develpment of writing proficiency of iranina pre-intermediate efl learners
abstract the present study was conducted to investigate the effect of using model essays on the development of writing proficiency of iranian pre-intermediate efl learners. to fulfill the purpose of the study, 55 pre- intermediate learners of parsa language institute were chosen by means of administering proficiency test. based on the results of the pretest, two matched groups, one as the expe...
Standard Model Higher Order Corrections to the WWγ/WWZ Vertex
Using the S–matrix pinch technique we obtain to one loop order gauge independent γWW and ZWW vertices in the context of the standard model, with all incoming momenta off–shell. We show that the vertices so constructed satisfy simple QED–like Ward identities. These gauge invariant vertices give rise to expressions for the magnetic dipole and electric quadrupole form factors of the W gauge boson,...
متن کاملSearches for Physics Beyond the Standard Model at Colliders
All experimental measurements of particle physics today are beautifully described by the Standard Model. However, there are good reasons to believe that new physics may be just around the corner at the TeV energy scale. This energy range is currently probed by the Tevatron and HERA accelerators and selected results of searches for physics beyond the Standard Model are presented here. No signals...
