Test beam for LHCb
Video about LHCb experiment and the recent test of their detector using Super Proton Synchrotron. LHCb experiment is one of six particle detector experiments aimed to measure CP violation in the interaction of b-hadrons (hadron containing b quarks).
Other interesting things in ArXiv (12 Jun 2009)
Wayne Hu. Acceleration from modified gravity: lessons from worked examples. The main question Wayne Hu discusses in this minireview is “How can we distinguish dark energy from modified gravity theories if the former and the latter provide the same predictions for cosmological dynamics?” He is particularly focused on DGP and models. His answer is the [...]
Other interesting things in ArXiv (11 Jun 2009)
Basically, there were so many interesting and useful papers (or at least they were useful for me) – lecture notes, reviews – that it will give me hard time posting reviews of all of them here – since I am lazy, I’ll just try to list some of them. Umut Gursoy et al. “Thermal Transport [...]
Notes on strongly coupled QCD in the continuum
By continuum here we mean using methods different from lattice QCD, which is currently our main instrument for quantitative understanding of QCD physics at strong coupling. What can we actually do apart from lattice simulations to study properties of QCD in this regime? Not much really. As recent minireview paper by M. Pennington explains, one [...]
Tour of Ares IX
Jim Halsell (former astronaut) takes Miles O’Brien on a tour through the various components of the new NASA Ares IX rocket.
This and that in ArXiv on Monday
Due to unbelievable overload of the last days let me simply list the recent papers in ArXiv that I found the most interesting: 1. Quantum information T. Tilma el al., “Is entanglement a critical resource for quantum metrology?” Can we beat the shot-noise limit (and get to the Heisenberg limit) in quantum metrology by playing [...]
Jim Simons and C.N. Yang interviewed by Bill Zimmerman
… about math (geometry)/physics interplay. Yang: there are two types of modern math books – the ones which you cannot read beyond the first page and the ones which you cannot read beyond the first sentence. Stinrood is of the latter kind. LOL Simons organizes new institute (6 faculty members, around 30 visitors per year), [...]
Workshop on tests of gravity in Case Western – day 2 and Arkani-Hamed’s talk
The second day of the Workshop on Tests of Gravity (and here is my blog post about the first day) was mostly devoted to analog models (Bill Unruh, Michael Uhlmann, George Pickett) and models of modified gravity (Nima Arkani-Hamed, Justin Khoury, Stacy McGaugh, Ted Jacobson, Levon Pogosyan and Mark Wyman). Regarding analog models I don’t [...]
Workshop on tests of gravity at Case Western – day 1
Dear friends, I am sorry for being rather quiet for a while. As many of you may already know, my laptop has decided to enter coma during the trip, as a result, I was left without appropriate internet access (sporadic use of Pascal Vaudrevange’s computer is not counted, thanks, Pascal!). Although the laptop tried to [...]
Real-time gauge/gravity duality
Balt van Rees from the U. of Amsterdam continues the discussion of non-equilibrium AdS/CFT we have started not so long time ago. Since his recent paper with Skenderis was one of the major achievements in the field, I highly recommend going through his post. Dmitry. Our recent paper Real-time gauge/gravity duality offers a prescription for [...]
