seminar tomorrow 11 am : Anisotropy Studies with the Pierre Auger Observatory
by Aart Heijboer 29 Feb '12

29 Feb '12

Hi all, Tomorrow at 11 am in h320 there will be a seminar by Stephan Schulte, who is interviewing for a post-doc position in our group. Title and abstract are below. I'd appreciate it if you come and ask questions! best regards, Aart. Anisotropy Studies with the Pierre Auger Observatory Stephan Schulte - RWTH Aachen University The Pierre Auger Observatory (PAO) in Malargüe (Argentina) reconstructs the arrival directions and energies of cosmic rays with energies exceeding 10^{18} eV. Under the assumption that the primary particles at the highest energies are only minimally deflected by the intergalactic magnetic field, it can be tested whether their arrival directions overlap with astronomical objects. In this context the PAO has observed a correlation of ultra high energy cosmic rays (UHECR) with nearby active galactic nuclei (AGN). In this talk a complementary approach is chosen. To this end, Autocorrelation methods are studied. They have the advantage of being independent of source and propagation models predicting the distribution of the arrival directions of UHECRs. However, to discover the assets and drawbacks of each method a Monte Carlo study is performed using simulated data sets based on a few of these modes. In the end, we compare the result when applied to data to the one of the catalogue-dependent correlation analysis by using the same event set.

[Theory-center] Reminder: theory center meeting Feb. 24
by Eric Laenen 12 Feb '12

12 Feb '12

Dear colleagues, a reminder that a Theory Center Meeting is scheduled for friday, 24-2-2012, in Nikhef. As usual, please register at http://www.nikhef.nl/pub/theory/registration/index.php See below for the agenda. I look forward to see you there. Best wishes, Eric --------------------------------------------------------------------------------------- Agenda Feb. 24 * Time: 10.00 - 17.00 * Talk 10.30-11.00, H320 Wilco den Dunnen "Linearly polarized gluons and the Higgs transverse momentum distribution" * Time: 15.00 - 16.00 Student meeting/discussion Tiago Nunes da Silve (RuG): "The phase diagram of QCD-like theories" The idea of the seminar is to give the audience an overall view of the phase diagram of QCD-like theories. In the first part of the seminar I'll talk about chiral symmetry and confinement. I will then introduce the order parameters associated with chiral symmetry breaking and confinemente/deconfinement transitions and show the picture we have so far for the phase diagram in the N_f - T plane. In the second part of the seminar I'll talk about the renormalization group flow and the possibility of a conformal window for QCD-like theories with large N_f. To conclude, I'll talk about theories with large chemical potential and color superconductivity. * Talk 16.30-17.00, H320 N.D. Hari Dass (Chennai Math. Institute) "Minimum uncertainty states" After a discussion of the so called 'Heisenberg Microscope' which heralded the notion of an uncertainty principle, I will discuss the modern variant wherein canonically conjugate variables are simultaneously measured. I will then address the issue of states saturating the bound. After giving a few examples which indicate that perhaps for entangled states, the minimum is not reachable, I will discuss the generality of this connection. A variational method that elegantly addresses such issues will be presented. I shall conclude by briefly mentioning the so called 'Entropic Uncertainty Relations' This is work done with Aditi Sheel and Tabish Qureshi. * 17.00 Borrel _______________________________________________ Theory-center mailing list Theory-center(a)nikhef.nl https://mailman.nikhef.nl/mailman/listinfo/theory-center
