Накратко на български
Свойствата на топ кварка и търсенето на неутрални Хигс бозони се анализират чрез данните от детектора CMS в ЦЕРН. Тези изследвания помагат за разбирането на работата на ускорителя и за допълване на Стандартния модел в физиката на частиците.

Цел на проекта
The Compact Muon Solenoid (CMS) detector is one of the High Energy Physics detectors of the Large Hadron Collider (LHC) accelerator of European Organisation for Nuclear Research (CERN). LHC will collide protons at a centre of mass energy of 14 TeV with hig h luminosity, while CMS is a collaboration of more than 160 universities and research centres of 36 countries. CMS will start its operations in June 2007 when LHC will provide data; until then, the main task will be to have the detector and the Tracker in p articular, ready for the first collisions. After that, the commissioning of the detector will begin followed by the data taking (2008). The intention of the project here presented is to participate in all these steps in order to be ready to do physics analysis with data at CMS, once the performance of the Tracker subdetector is understood. The Tracker subdetector constitutes the main tool to tag b quarks (b-tagging), the principal decay product of high mass particles in LHC. Its construction, readout and calibration will be a total challenge for the CMS collaboration and at the same time, the main device to perform the foreseen physics program. This project intends to participate in the qualification and calibration of the Tracker.The study of the top quark p roperties represents a basic reference to understand the performance of CMS and LHC, given the high cross-section of the top-antitop pair production foreseen. The objective is to begin with the study of the dileptonic channel in all its aspects, and to ext end it afterwards to the semileptonic one. The search for Higgs bosons is the last piece of the SM puzzle and its natural extension, the MSSM. The process bbH/A -> bbbb, is the most likely to happen for neutral Higgs bosons in the MSSM inside the LHC framework. Therefore, this analysis has been included in the Physics Technical Design Report (PTDR), foreseen for the year 2006, which will describe the physics potential of CMS.
