“…The parton energy loss in a quark-gluon plasma created in Pb–Pb collisions at s=2.76 TeV is discussed based on the measurements of semi-inclusive charged particle jets correlated with a high- pT hadron, the nuclear modification factor ( R AA ) for identified hadrons and D-mesons. …”

“…Jet production in heavy-ion collisions at relativistic energies provide an excellent opportunity to study the in-medium modification and the energy loss mechanism of partons in strongly interact- ing quark-gluon plasma. A detailed overview of jet results from CMS experiment for PbPb, pp and pPb collisions are presented in this paper. …”

“…Lo stato finale $\tau \tau$ contribuisce altres\`i alla ricerca di un bosone di Higgs neutro (h) del modello supersimmetrico minimale (MSSM), negli eventi in cui sia prodotto in associazione con due b quark jets. Saranno presentati i risultati ricavati per $H (h) \rightarrow \tau \tau$.\\ In linea con l'esposizione legata ai risultati di analisi che coinvolgono stati finali con b quark jets e per confronto con $h \rightarrow \tau \tau$, sar\`a presentato il punto sulla ricerca di (h, H, A) $\rightarrow b \overline{b}$, dove h,H ed A sono gli stati scalari e pseudoscalare neutri previsti da MSSM…”
