Study of DiMuon Rare Beauty Decays with ATLAS and CMS

The LHC experiments will perform sensitive tests of physics beyond the Standard Model (BSM). The investigation of decays of beauty hadrons represents an alternative approach in addition to direct BSM searches. The ATLAS and CMS efforts concentrate on those B-decays that can be efficiently selected already at the first and second level trigger. The most favorable trigger signature will be for $B$-hadron decays with muons in the final state. Using this trigger, ATLAS and CMS will be able to accommodate unprecedentedly high statistics in the rare decay sector. These are purely dimuon decays, and families of semimuonic exclusive channels. Already with data corresponding to an integrated luminosity of \ensuremath{1 fb^{-1}}, the sensitivity in the dimuon channels will be comparable to present measurements (world average). The strategy is to carry on the dimuon channel program up to nominal LHC luminosity. In particular the \ensuremath{B_s \to \mu\mu} signal with \ensuremath{\sim}5 sigma significance can be measured combining low luminosity \ensuremath{10^{33}cm^{-2} s^{-1}} samples with those of one year of LHC operation at a luminosity of \ensuremath{10^{34}cm^{-2} s^{-1}Comment: Submitted for the SUSY07 proceedings, 4 pages, 2 figures, 4 table

Analysis of videofluoroscopic variables affecting swallowing safety and efficiency in ophl patients

Open partial horizontal laryngectomy (OPHL) could represent a valuable alternative to total laryngectomy for selected laryngeal carcinoma. In long-term, occasional aspiration ranges from 12.9 to 67% after OPHL [1]. Rate of aspiration pneumonia can reach the 21.7% [2]. Main causes of swallowing impairment vary from a defective glottic closure to a reduced upper esophageal sphincter (UES) opening. At the present time, only one study analysed spatial and temporal videofluoroscopic variables to evaluate factors affecting postoperative aspiration. No studies before have compared videofluoroscopic variables between OPHL patients with and without dysphagia
