Framework e produzione

No big news; Lustre almost full. Ugs will solve 1% of the problems. Use GPU for fitting and speeding up analysis: test the frame in Bari, and, in case, develop Padova frame with LHCb and Fermi people. MZ : Couple of students are going to use the cloud. FF: you could start as soon as today, I can work new frame this afternoon

Attivita' di analisi

B physics

SL : workshop in CERN . Several presentation on possible analyses. outcome: lack of people at work. How to attract people in the group ? FS presented a set of possible measurements: Double Gluon Splititng, mixing. Angular analysis: extrapolations not encouraging: 40% more events wrt 8 TeV. Use also this year data before publication. More precise estimation are needed.

Dark Matter

No news

Dibosoni, VZ risonante (V=W,Z)

LB : unblinded., o significant excess. Nevrtheless the limit is competitive. Started ARC review, go for approval asap, should be before EPS dead line (end of june).

hh4b non risonante

TD : Preapproval one week ago. Questions on optimization of the BDT. Now reach 36 times the Standard Model. Waiting for ARC interaction. Other optimizations ongoing.

Same sign leptons

UG : mu-e analysis is almost ready, soon at the same level of mu mu. Presentation in one or two week. Excess established at 4.8 sigma with full statistics. Today approval single top+Higgs (same topology)

Seesaw a 13 TeV

ET : Carla allowed in the author list after a long discussion

EPR

Isolamento muoni

Flavor tagging

Trigger

Detector

FG : ageing task force meeting this afternoon. Some polluting material has been identified. Try to unerstand the size and danger of these source of degradation. GIF stopped. This week the test of the first bicell should be over. The bicell ages much less than the MB1 exposed at the GIF (degradation of ~ 10% when exposed to full LHC HL radiation). Work of LEMMA with MB2 will improve our understaning:MB1 tested in GIF, MB3 in LNL, MB2 now thanks to LEMMA. Local monitor if ageing exists and how much is going on. PC : how long it will take before completion of this work ? All in all the measured ageing does not seem to affect the detector operation. FG : external chambers of external wheel will lose in a sensible way. If the loss reaches 80% you won't be able to trigger. True that they are helped by CSC in the forward region. All test we do are without recirculation. In CMS we recirculate, therefore the effect could be amplified. Difficult to assess time, depends on GIF availability, etc. PC : this activity is taking resources but it is not publicly discussed in commissione uno. AM : activity of whom ? Franco Gonella, Barcellan, people involved in analysis ? PC : the sum of it. FG : we did not need financial support and we did not ineterfere with other activities up to now. UG : we should understand if we expect any clash in the future. FG : in few months the work should be over. Two problems : test at LNL, behaviour at P5.

A.O.B.:

MZ : presentation on DML next Tuesday FS : next Thursday we try to have a Laureandi session.
