Bfys Meeting Friday 18 january at 9:30 in N328 and on EVO* Paper introduction and discussion: 9:30 "A search for D+(s) to pi+mu+mu- and D+(s) to pi-mu+mu+ decays" by Francesco Dettori http://cds.cern.ch/record/1504407 Veldhoven rehearsals: 10:30 "A new window for new physics in Bs decays to two muons" by Rob Knegjens 11:00 "The Bs meson decay in two muons: a search for rare beauty" by Serena Oggero 11:30 "Measurement of the angle gamma in the unitary triangle in time-dependent Bs to DsK decays at the LHCb experiment" by Manuel Schiller The presentations will be available (protected under lhcb, etc.) on the Nikhef agenda page and comments can be directly mailed to the speakers. Best regards, Tjeerd *)Today Vidyo could not provide the same service as EVO in our meeting room at Nikhef, therefore I decided to book this meeting again on EVO. Universe is the community, as LHCb has been removed. As a test we can open a room in Vidyo on Friday at 12:00. ========================================================= http://agenda.nikhef.nl/conferenceDisplay.py?confId=2361 ========================================================= You have BOOKED a meeting in SeeVogh Research Network (http://research.seevogh.com).

[Bfys-physics] Open day
by Jacco de Vries 26 Sep '13

26 Sep '13

Dear all, Saturday 5 Oktober will be the date of the Nikhef open day. If you would like to participate at the bfys stand (in the construction hall, H070) to run some experiments, or enthusiastically answer a lot of questions, you are very welcome! So far, I have 'collected' the following people: - Veerle - Pieter - Siim - Vasilis - Roel Please let me know if you plan to be there (and you're not already on the list), and I'll make sure you get a T-shirt, nametag, and everything that Nikhef has to offer us. Thanks, Jacco
