This note describes the preparations towards searching for the production of a Z boson in association with a photon at the LHC with s = 10 TeV in the first 200 pb −1 of data. A sensitivity analysis investigating a search for anomalous couplings of …
Applying a general Artificial Neural Network approach, the possibility to discriminate neutral pions (π0) from photons was studied using information from both ECAL and Preshower subdetectors. For unconverted particles the obtained neutral pion …
The Little Higgs model gives an alternative solution to the fine-tuning problem present in the Standard Model (SM) of strong and electroweak interactions. The model invokes several new particles of TeV mass range, the lightest among them being a …
This paper contains the first realistic estimate for the CMS sensitivity to Flavour Changing Neutral Currents (FCNC) in the top quark sector. The non-Standard Model decays t-Zq and t-γq (where represents or quarks) have been studied at 14 TeV …
A measurement of the branching fraction R s =Γ ss̄ /Γ had of the Z 0 into strange quarks was made. For this measurement energetic φ 0 mesons decaying into K + K − and charged kaons were used to tag the presence of e + e − → Z 0 → ss̄ events. 1.4 …
