    Carl Brannen is having a real triumph in Hawaii

    He and the famous Japanese physicist Koide are giving talks back to back today and their slides are on line. It seems like on about half his slides (many many anyway) Koide is referring to two equations of Brannen's which Koide has named "the Brannen first relation" and "the Brannen second relation".

    The discussion is in Particle Physics subforum, but since Carl B often posts here in Beyond it seems appropriate to notice this bit of news. Read Kea and arivero's discussion with Carl here:

    Our "campaign for Koide awareness" is important because it runs against one of the more fundamental prejudices of current theory: that as masses are got down from the GUT scale, no relationship can be seen in the infrared, low energy, limit.

    More news (and congratulations where appropriate) about doings of people who sometimes post in the Beyond forum.

    Christine has completed the first year of blogging---pretty nice blog too.

    Bee Hossenfelder is obviously having a great time at Perimeter.
    Her furniture finally arrived from Santa Barbara (congratulations:smile: ).

    Bee just posted a paper on arxiv
    Phenomenological Quantum Gravity
    which will be published in the SUSY 06 proceedings.

    F-H just posted a paper written with several others including Carlo Rovelli.
    He finished the program he was in at Marseille and is now working on PhD at Nottingham---where John Barrett is.

    Anybody think of more news?

    Where are the Koide slides?

    The Koide presentation:

    The speaker before us, Paul Harrison of Warwick, was very closely associated with our stuff, of course from a different point of view, "tribimaximal mixing angles". His talk was fascinating (despite my feeling of impending doom while listening to it).

    He was using matrices a lot like the ones that show up in my slides, particularly what he calls the "democratic operator", I call the "democratic primitive idempotent" in my book on the density operator theory:

    I feel that we could have sat around talking about neutrinos and finished each others sentences.

    I also attended the talk on whether or not string theory can predict anything and will blog it when I get the chance. I hate to type through someone's hard won talk, even if it is dead wrong, obvious and or boring.

    Speaking of which, here's my abstract:

    When I typed in the above abstract, I was so breathless about the possibility of meeting Koide that I quite forgot to mention anything about density operator theory. And partly I was afraid they'd put me into "beyond the standard model" sections which are too far divorced from experiment for me to really fit.
