- ICHEP 2016 starts in Chicago this week. Talks about the new diphoton results are scheduled for 9am (Chicago time) Friday. There will also be talks later in the day at CERN (5pm Geneva time), scheduled as part of this summer’s TH institute. Consulting my prediction here (although I had the plenary vs. parallel wrong), I think it’s very clear that these will be negative results for the supposed 750 GeV bump. See Resonaances for discussion of the significance of this.
- Last year I heard Nima Arkani-Hamed talk here about “Nnaturalness”. The paper is now out.
- There’s a very interesting profile in Nautilus of Fotini Markopolou, who left theoretical physics to work on a startup in England.
- At Quanta magazine, Natalie Wolchover has a nice article about intriguing new neutrino results. With nothing unexpected showing up at the energy frontier being explored by the LHC, in coming years it may very well be the neutrino sector, which can be explored at much lower energies, where one should look for something new.
- Strings 2016 is starting in Beijing in a few hours. Schedule here, talk titles here.
Update: Videos of the Strings 2016 talks are becoming available here. The talks of the first day featured little string theory (except for a historical talk by John Schwarz). A major theme was 3d quantum field theory, with Witten and Costello talking about the same new ideas starting with Chern-Simons theory, and Seiberg talking about dualities in 3d qft.
Update: Slides are here. Tuesday started off with entanglement entropy and tensor networks. I confess that not only do I not see what this has to do with string theory, but have trouble seeing what it has to do with anything. The connection with quantum gravity using tensor networks seems vaguely to recall the much more well-motivated spin networks of LQG, which string theorists always denounced as not exhibiting a Lorentz invariant ground state. Now it’s the string theorists promoting this kind of network structure, noticing the same problem they used to denounce as convincing evidence their competitors had it all wrong. The world is a strange place.
Update: New Scientist has a quote from me saying the obvious thing about Nnaturalness. Blogging likely light to nonexistent for the next week, I’ll be traveling, listening to music in Nashville, as well as up in the mountains of Virginia/Tennessee,
