Seminare de DPNC ================ Mercredi, 19 Mai 1999 17.00 - Auditoire Stuckelberg Universite de Geneve Departement de physique nucleaire et corpusculaire 24, quai Ernest-Ansermet 1211 Geneva 4 Tel. 022 702 6273 Fax 022 781 2192 ****************************************************************************** Sujet:Cosmics with L3, the L3+C experiment Par: Prof. Dr. P. Le Coultre, ETH, Zuerich Resume: The L3+C experiment takes advantage of the unique properties of the L3 muon spectrometer to get an accurate measurement of cosmic ray muons 30 m underground (low energy threshold compared to other underground detectors, unrivalled momentum resolution over a wide momentum range). New results for a variety of fundamental topics in cosmic rays, astrophysics and particle physics are expected.
