We meet every Monday at 1.30pm to discuss the new developments in the fields of research relevant for GRAPPA members and affiliates. The idea is to discuss briefly, with the help of a projector, the results of ~5 interesting papers recently appeared on the arXiv, or anywhere else. Please choose one posted e.g. this week in your field and tell us about it in 5-10 minutes. Feel free to join us even if you haven't read anything.

    I think it is useful to compare what IC79 alone can do with respect to IC40 and Amanda combined:
    Multiyear Search for Dark Matter Annihilations in the Sun with the AMANDA-II and IceCube Detectors, IceCube Collaboration: R. Abbasi et al.

    (1) I finally took at look at Bekenstein's story about table-top-quantum-gravity. http://arxiv.org/abs/1301.4322 I can talk about it briefly.

    (2) I also notice a few recent paper talking about the measured Higgs mass implies some possible instability of our vacuum. Here are a few of them. Anyone understands this?

    I'd like to discuss a paper about constraining primordial black holes via the stability of neutron stars within globular clusters:
