I am noticing in the arxiv a series of papers marked as Invited contribution to the book "Half a century of Supergravity” eds. A. Ceresole and G. Dall'Agata (CUP, to be published) Any idea about if the book has been published or if we have at least an index of the contents?

Furey's current work is continuation of her lectures in youtube, if someone comes here going for the "algebrological" path (happens once each ten years), go to her youtube channel.

Yep, as I mentioned there, the "84 fermions" idea comes from a counting of degrees of freedom of my advisor, LJ Boya, in some of his last drafts on representation theory and strings. The "duality" view, on the other hand, is my own half baking, the idea being that we could look both to...

In related news, I have updated the wikipedia page with the new (well, 2024) pdg measure, which was from the Belle measure that @ohwilleke noticed last year. It had not been moved since 2008 🙃 So it seems we are at Q = 0.66666446(508) Today it makes 20 years since the first mention in...

Hmm @Kea and @CarlB did mention this paper back in 2006 but I had not checked it. The generalised circulant in (3) still matches Koide, does it? I mean, if a,b defined a Koide circulant. Mitchell has suggested to look again into circulants and well, I agree they were pretty elegant; the trick...

Indeed I am a bit worried, lets see if they find some discrepancy with models.

She is surely retired (b. 1951), the arxiv only has some collaborations with Nielsen (b. 1941, we invited him in out lab time ago in the nineties). Surely not used to internet forums, because clearly she missed completely this thread. It is more infuriating that her previous paper on democratic...

honestly I have no idea. Usually C is more simple, symmetry wise, than R. So between C3 and R6... Also, it seems we need seven dimensions but in a very particular way, interpolating between six and eight.

My take on this. The fundamental reading is the collection of papers Modern Kaluza-Klein Theories and inside of them, the most fundamental is Witten 1981 "Search for a Realistic Kaluza-Klein Theory" Because it sets the framework to do non abelian gauge theories. A immediate reaction to it...

If it were possible to derive G out of h and c, should we start discussing with one is the derived and which ones are the two fundamentals? As we stand today, with a relationship between four constants, we consider that Planck Length is the derived one. But it is fun to consider eg that we...

I think that accelerating alpha decay for any particle is virtually impossible. Note that alchemists dream was to accelerate the decay alpha of Hg 201, whose half-life is about the universe lifetime

yep I did not go very deep on this on the paper; it was supposed to be a letter and I was expecting the referees to ask me to delete some section. But it is amusing that if one just ignores or corrects the charm failure, it goes better. It seems to me that your idea is to relate the failures to...

As I mentioned in the sBoostrap thread, I had put in a preprint some calculations of Koide masses using the original composite idea and they have happened to be published as Eur. Phys. J. C 84, 1058 (2024). https://doi.org/10.1140/epjc/s10052-024-13368-3, so as a collateral effect we now have...

The preprint about the sBoostrap from the point of view of SO(32) is now published as Eur. Phys. J. C 84, 1058 (2024). https://doi.org/10.1140/epjc/s10052-024-13368-3 if someone happens to need a reference some day. It includes also some review of Koide, as I said before, but I will discuss it...
