[Bfys-physics] Reminder Master Presentation Today
by Robert Fleischer 29 Aug '12

29 Aug '12

H331 at 14:00 Speaker: Philipp Frings Title: CP Violation in Charm Decays - A Signal of New Physics? Abstract: The detection of the Higgs boson is the last of a series of successes of the Standard Model. Nevertheless, there are reasons that suggest that the SM is incomplete. Search for vioaltion of the charge-parity (CP) symmetry is a good way to find new physics which could complement the SM. Measurements of the observable Delta A_CP = A_CP(D^0->K^+K^-)-A_CP(D^0 -> pi^+pi^-), which measures CP violation, deviate significantly from the Standard Model expectation and seem to be an indication that some new physics is in play. In this talk, we will use flavor SU(3) breaking to show that the measurement could also be accomodated in the Standard Model and is not necessarily a sign of new physics.

[Bfys-physics] Fwd: Informal Nikhef Higgs theory-experiment meeting (things you don't dare to ask but simply need to know)
by Marcel Merk 13 Aug '12

13 Aug '12

Dear Bfys friends, Since all CP asymmetries in the Standard Model arise via the Yukawa couplings of the Higgs field to the fermions the following discussion is in my opinion just as relevant for LHCb people as for Atlas people. Please see below, best regards, - Marcel ---------- Forwarded message ---------- From: Ivo van Vulpen <Ivo.van.Vulpen(a)nikhef.nl> Date: 1 August 2012 15:23 Subject: Informal Nikhef Higgs theory-experiment meeting (things you don't dare to ask but simply need to know) To: atlas-group(a)nikhef.nl, theory-wide(a)nikhef.nl, Marcel Merk <i93(a)nikhef.nl>, Niels Tuning <h71(a)nikhef.nl>, Aart Heijboer <aart.heijboer(a)gmail.com>, frank linde <f.linde(a)nikhef.nl> Hi colleagues, We're trying to organize an informal experiment-theory meeting where we can discuss some of the aspects/implications of the Higgs(-like particle) discovery. In some of the discussions the past weeks we noticed that some questions on theoretical implications are unknown to the experimentalists while they are mostly 'trivial' for the members of the theory group. Same holds for the experimental facts, interpretations and issues for theorists. If we can collect the most important questions from each community the 'other' group should be able to explain them within 2 x 30-45 minute presentation with discussion or so. We'll not be able to go into full depth on all issues, but exchanging the idea's and knowledge is the main goal. -------------------------- Date: Tuesday September 4th Time: 11:30-13:00 hours Where: Nikhef, H331 -------------------------- So: if you are a theorist and have an experimental question please send it to Eric/Marieke at least 1 week before the meeting. If you are an experimentalist send your question to Stan or me. Although this mail is only sent to to the Nikhef atlas and theory group, everybody from Nikhef that is interested is welcome to attend of course, so spread the word and collect questions form your colleagues in other groups. Regards, Marieke, Eric, Stan and Ivo

Dear all, I guess the PhD students have received the email below, before. This message is just to encourage you (PhD students) to join this excellent course, in case you are not yet an expert in C++. Please discuss with your supervisor if it would be a good idea to join. The course is given each year in January at Nikhef. best regards, - Marcel ---------- Forwarded message ---------- From: Joan Berger <jberger(a)nikhef.nl> Date: 1 August 2012 16:32 Subject: [Owc] [Promovendi] C++ course January 2013 To: promovendi(a)nikhef.nl Cc: Wouter Verkerke <verkerke(a)nikhef.nl> Dear PhD's, The next C++ and object oriented programming course targeted to Nikhef PhD students will be in January 2013. Friday January 4 - Unix/Batch Monday January 7 - C++ part 1 Wednesday January 9 - C++ part 2 Friday January 11 - C++ part 3 Monday January 14 - C++ part 4 Wednesday January 16 - C++ part 5 and will be given in room H239 at Nikhef by Wouter Verkerke. *** As knowledge of C++ is nowadays essential for all (experimental) HEP students, *** *** this course is strongly recommended to all 1st and 2nd year PhD students. *** PhD students in later years that are interested in following this course are also welcome.

[Bfys-physics] Breathalysers for CERN cars
by Antonio Pellegrino 30 Jul '12

30 Jul '12

Dear all, following up on the mail below, Eddy and I placed two breathalysers in each CERN car, as requested by Frence law since July 2012. The main purpose of this action was to prevent that users of our cars at CERN may be fined by the French police. If for any reason you end up actually using a breathalyser, please replace it with a new one. Ciao, Antonio P.S. Incidentally, in the process of placing the breathalysers in the two CERN Peugeots, I learned that I will never entrust any valuable property to any of our guys in Bldg. 13, since both cars had been displaced under their nose by the CERN parking service (piping work on one side and parking-stripes painting on the other) and none of them took notice, so a week ago Chiara had to look for the Peugeot 3726 and today I had to call the CERN parking service to locate the 3956!? ---------- Forwarded message ---------- From: Anu Liisa Saarelainen <anu.liisa.saarelainen(a)cern.ch> Date: 25 June 2012 15:01 Subject: Breathalyser for CERN cars To: Loic Brarda <Loic.Brarda(a)cern.ch>, Bernard Corajod <Bernard.Corajod(a)cern.ch>, Tengiz Kvaratskheliya <Tengiz.Kvaratskheliya(a)cern.ch>, Rolf Lindner <Rolf.Lindner(a)cern.ch>, Pierluigi Campana <pierluigi.campana(a)lnf.infn.it>, Eddy Jans <eddy.jans(a)cern.ch>, Grzegorz Polok <Grzegorz.Polok(a)cern.ch>, Hugo Ruiz Perez <Hugo.Ruiz(a)cern.ch>, Gerard Decreuse <Gerard.Decreuse(a)cern.ch>, Cedric Fournier <Cedric2.Fournier(a)cern.ch>, Carmelo D'Ambrosio <Carmelo.D'Ambrosio(a)cern.ch>, Iouri Guz <Iouri.Gouz(a)cern.ch>, Evgeny Gushchin <evgeny.gushchin(a)cern.ch>, Kirill Kachnov <Kirill.Katchnov(a)cern.ch>, Burkhard Schmidt <Burkhard.Schmidt(a)cern.ch>, Nikolai Bondar <nikolai.bondar(a)cern.ch>, Marcel Merk <marcel.merk(a)nikhef.nl> Dear all, As you may already know, as from 1 July 2012, any driver of a motorised road vehicle in France must be in possession of a breathalyser in full working order. Please note that drivers of vehicles belonging to or leased by the Organization may obtain breathalysers by completing a material request in EDH using the reference number 50.64.03.001.6.
