Here our last MIP poll: https://www.physicsforums.com/showthread.php?t=282166 By the end of this month I'd like to have a short list of promising first quarter papers. Ones that appeared Jan-March 2009 and stand a good chance of turning out to be important or valuable for future research. That's something we will be able to gauge approximately in six months or a year from now, just by checking the citations, and also our subjective judgment will be clearer in retrospect. But for now it's difficult if not impossible to be sure. We can only guess. One thing that interests me is who the good guessers are. In the last MIP poll, if we go by the citation counts accumulated so far, one of friend's guesses turned out way ahead of the rest (it now has 16 cites compare with 4 for the next highest.) So which of the first quarter (nonstring QG) papers get nominated? I have four to suggest at the moment. Conrady Freidel http://arxiv.org/abs/0902.0351 Barrett et al http://arxiv.org/abs/0902.1170 Bonzom http://arxiv.org/abs/0903.0267 Marugan et al http://arxiv.org/abs/0902.0697 There is also a paper by Claudio Perini and Elena Magliaro that is in the works and could appear soon. If it appears this quarter I woud definitely include it. Perini presented the results at this Perimeter talk here: http://pirsa.org/09020023/ Maybe the video, audio, and pdf files here can serve as a place-holder for that paper Graviton propagator from EPRL spinfoam model Claudio Perini "We derive geometric correlation functions in the new spinfoam model with coherent states techniques, making connection with quantum Regge calculus and perturbative quantum gravity. In particular we recover the expected scaling with distance for all components of the propagator. We expect the same technique to be well-suited for other spinfoam models." It's an impressive talk. One of the things that persuades me the LQG low energy thing will be pretty much wrapped up by the time Rovelli lectures on it at the Corfu school.
