Abstract:

Events with high energy isolated electrons, muons or tau leptons and missing transverse momentum are studied using the full e ^± p data sample collected by the H1 experiment at HERA, corresponding to an integrated luminosity of 474 pb ^-1. Within the Standard Model, events with isolated leptons and missing transverse momentum mainly originate from the production of single W bosons. The total single W boson production cross section is measured as 1.14±0.25 (stat.)±0.14 (sys.) pb, in agreement with the Standard Model expectation. The data are also used to establish limits on the WW γ gauge couplings and for a measurement of the W boson polarisation. © 2009 Springer-Verlag / Società Italiana di Fisica.

The race for supersymmetry: Using mT2 for discovery

Physical Review D Particles Fields Gravitation and Cosmology 80:7 (2009)

Authors:

AJ Barr, C Gwenlan

Abstract:

We describe how one may employ a very simple event selection, using only the kinematic variable mT2, to search for new particles at the LHC. The method is useful when searching for evidence of models (such as R-parity conserving supersymmetry), which have a Z2 parity and a weakly interacting lightest parity-odd particle. We discuss the kinematic properties which make this variable an excellent discriminant against the great majority of standard model backgrounds. Monte Carlo simulations suggest that this approach could be used to discover supersymmetry with somewhat smaller integrated luminosities (or perhaps lower center-of-mass energies) than would be required for other comparable analyses. © 2009 The American Physical Society.
