[Theory-seminar] Reminder: theory seminars this week
by Kalliopi Petraki 15 Apr '13

15 Apr '13

Hello, We will have two theory seminars this week, please see the information below. Note the unusual day for the first, unusual room for the second. Best, Kallia ------------------- Date/place: Tuesday 16, 2pm, H331 Speaker: Gianfranco Bertone (UvA) Title: The quest for Dark Matter Abstract: After a brief review of the Dark Matter problem in Cosmology and its possible connection with Particle Physics, I will discuss the prospects for detecting Dark Matter at the LHC and with the upcoming generation of Astroparticle experiments, focusing in particular on the complementarity of direct, indirect and accelerator searches, and showing with an explicit example how to combine them in a self-consistent way. I will conclude with a brief overview of the research activities of the new GRAPPA Institute at the U. of Amsterdam. ------------------- Date/place: Thursday 18, 2pm, N328 Speaker: Christophe Ringeval (Louvain) Title: Early universe cosmology after Planck 2013 Abstract: The 2013 release of the Planck satellite data has provided unprecedented measurements of the Cosmic Microwave Background anisotropies and much more. Together with a few new observables at our disposal, these results can now be used to improve our understanding of the early universe. After an introduction to CMB physics and a selected summary of the Planck 2013 results, we will illustrate over two examples, cosmic strings and inflation, how the Planck data give us a window to very high energy physics provided one uses enough precise and systematic theoretical predictions. -------------------

[Theory-seminar] Extra colloquia by Christoph Weniger and Claudia Hagedorn on Thursday April 11th
by Crommentuijn, Anne-Marieke 09 Apr '13

09 Apr '13

Dear all, This Thursday, April 11th, there will be extra colloquia by Christoph Weniger and Claudia Hagedorn. Speaker: Christoph Weniger Time & Location: 11:00 - 12:00 in room A1.10 Title: Indirect searches for dark matter Abstract: Unraveling the nature of dark matter is one of the most exciting tasks of current fundamental and astroparticle physics. The currently leading hypothesis for particle dark matter - weakly interacting massive particles(WIMPs) - is probed in a multitude of ways. Among these probes are indirect searches for signals in the flux of cosmic- and gamma-rays. Recently, we identified a tentative gamma-ray line in the Galactic center observations of the Fermi LAT, which would be an unequivocal smoking-gun signature for dark matter annihilation in the Universe. One year after discovery, the signature is still as ambiguous as it could be. I discuss recent experimental and theoretical developments and show how the situation could be clarified until end of next year. Speaker: Claudia Hagedorn Time & Location: 15:00 - 16:00 in room C1.112 Title: The mystery of flavor Abstract: I will discuss the peculiar features of the fermion mass and mixing patterns and point out crucial differences between quarks and leptons. I will explain why and how flavor symmetries can play the key role in understanding these features. Furthermore, I will briefly mention the impact of such symmetries on flavor-violating processes in theories beyond the Standard Model in which new gauge interactions and/or additional particles are in general present. _____ Universiteit van Amsterdam Institute of Physics (IoP), FNWI drs.

Speaker: Rikkert Frederix Title: Tools for LHC phenomenology -- the road from postdictions to predictions Abstract: The world's largest particle accelerator, the LHC, has been running extremely well during the last couple of years. The data recorded by the experiments is of extremely high quality, surpassing most expectations. To get the most out of the data by comparing them to theory, predictions of evenly high quality are a must. In this talk I'll discuss the FxFx merging procedure, implemented in the aMC@NLO program, that allows for the simulation of events at unprecedented precision. _____ Universiteit van Amsterdam Institute of Physics (IoP), FNWI drs.

[Theory-seminar] Extra colloquium by Chiara Arina at 3pm in room B0.201.
by Crommentuijn, Anne-Marieke 03 Apr '13

Dear all, This Thursday, April 4th, there will be an extra colloquium by Chiara Arina at 3pm in room B0.201. Speaker: Chiara Arina Title: Dark Matter phenomenology: from particle- to astro- physics Abstract: At present time Cosmology has entered the precision era and astroparticle experiments have achieved unprecedented sensitivity, while particle physics has entered the LHC era. A link between these scales is the dark matter, interpreted as a weakly interacting massive particle (WIMP). I will discuss how to extract constraints and properties on WIMPs by taking advantage of the available data, both in a phenomenological approach and in theoretically motived framework, and give future prospect for detection. _____ Universiteit van Amsterdam Institute of Physics (IoP), FNWI drs.

[Theory-seminar] Colloquium Friday
by Eric Laenen 03 Apr '13

03 Apr '13

Dear theorists, this is to alert to you an interesting colloquium on Friday by Cecilia Jarlskog [Lund] " Two Nobel stories: Marie Curie 2 - Ernest Rutherford 1" Two important historical happenings about 100 years ago were the discovery of the atomic nucleus by Rutherford and the award of Nobel Prize in chemistry to Marie Curie. Based largely on material in the Nobel archives, I will discuss these events and the question of why Curie got two Prizes but the discovery of the atomic nucleus was not honored. http://agenda.nikhef.nl/conferenceDisplay.py?confId=2406<http://www.google.com/url?q=http%3A%2F%2Fagenda.nikhef.nl%2FconferenceDispl…>
