What are these groups like SU(2) and E8XE8 etc. Can anybody explain it with full details and also give pre-requisite knowledge.

Some good books

"Full details" :rolleyes: Not bloody likely. Try Carter, Segal, and MacDonald, Lectures on Lie Groups and Lie Algebras for an overview and then Bump, Lie Groups for details on some of the most important ideas. You can find details on various approaches in many other books as well, such as Gilmore, Lie Groups, Lie Algebras, and Some of Their Applications.

Caution: at any given moment, Wikipedia articles may be quite impressive or they may be terribly misleading and inaccurate. In particular, be aware that mathematical cranks exist and wikishilling is a problem in the math pages at WP.

Thread 'The "electroweak eta meson"'

This is an alert about a claim regarding the standard model, that got a burst of attention in the past two weeks. The original paper came out last year: "The electroweak η_W meson" by Gia Dvali, Archil Kobakhidze, Otari Sakhelashvili (2024) The recent follow-up and other responses are "η_W-meson from topological properties of the electroweak vacuum" by Dvali et al "Hiding in Plain Sight, the electroweak η_W" by Giacomo Cacciapaglia, Francesco Sannino, Jessica Turner "Astrophysical...

Thread 'Black to white transition in LQC'

In LQG and LQC there are solutions called "black to white transition". I'll add some references: (Rovelli)https://arxiv.org/abs/1905.07251 (Rovelli)https://arxiv.org/abs/2302.03872 (Rovelli)https://arxiv.org/abs/1803.06330 (Rovelli)https://arxiv.org/pdf/1802.04264 (Rovelli)https://arxiv.org/abs/2108.12823 https://arxiv.org/abs/2304.02691 https://arxiv.org/abs/2110.07589 https://arxiv.org/abs/2009.01788 https://arxiv.org/abs/1911.12646 https://arxiv.org/abs/1801.03027...

Thread 'Discussion of "Two-Time Physics" (I. Bars) and its potential cosmological implications'

Hello everyone, I am seeking to better understand the conceptual foundations and potential consequences of "Two-Time Physics" (2T-physics), as developed by Itzhak Bars and others. My interest was sparked by a recent paper that attempts to explain anomalous results in particle physics (apparent superluminal propagation of virtual photons) within the framework of 2T-physics: Paper: https://arxiv.org/abs/2408.02696 Key quote from the abstract: *"...the problem... can be solved naturally...
