چکیده
The effect of external as well as internal bremsstrahlung radiation in H ! ZZ ! 4e channel is studied in full detector simulation. A method is proposed for external and internal bremsstrahlung recovery, allowing us to use 95% of electrons within j E=pgen 1 j 0.2. It is shown that traditional E=p and isolation cuts can be implemented with 90% efficiency, but that precise mass reconstruction is achievable with higher efficiency without applying such cuts. Z and Higgs reconstruction efficiencies are given, in presence of jet background from the underlying event. The final efficiency for Higgs reconstruction within 2 amounts to 37%, with a resolution of 0.85 GeV for a realistic PbWO4 calorimeter. The resolution drops to 1.28 GeV for a pessimistic version of the calorimeter resolution.

Some properties of a 90% C2H2F4 gas mixture, used to operate resistive plate chambers in avalanche mode, are determined by comparing the experimental results with the prediction of simple analytical calculations. The fast charge distribution of the signal induced on pick-up electrodes is reproduced by means of a Monte Carlo simulation of the avalanche development. In addition predictions for a ...

Discovery limits for the neutral SUSY Higgses in the l + jet + Emiss t final state from A;H; h ! are calculated as a function of mA and tan . For the selection efficiencies and jet rejection factors results obtained from a detailed simulation of the CMS calorimeter are used. Possibility to suppress the irreducible Z; ! background with b-tagging in the associated production channels is studied. ...

We investigate the possibility of reducing the data size of the electromagnetic calorimeter(ECAL) of CMS. The Selective Readout is applied first to reduce the data size at a manageable level. Then various data compression methods are considered, and their performances are estimated using the data from the full simulation of the ECAL system. A reduction of the average event size by a factor of t...

This note summarizes the results of a study of the identification of theH !WW !`` ` `0 signal for MH 0 = 170 GeV/c. This study is motivated by the papers written by M. Dittmar and H. Dreiner [1][2]. We carried out a similar study using Pythia to generate events and CMSIM calorimeter simulation for the jet veto, and compared with their results. We also show some comparison between Pythia and IS...

The possibility to determine sparticle masses in the 3l + no jets + Emiss T final states from ~ 1 ~ 02 pair production is studied. It is based on the kinematics of ~ 02 ! l+l ~ 01 and ~ 02 ! l ~l L;R ! l+l ~ 01 leptonic decays. The analysis is carried out within the framework of the minimal SUGRA model, where the mass measurement of the lightest neutralino ( ~ 01) allows to constrain the common...
