has an Jenny Nielsen's theory interaction between electroweak gauge fields and the gravitational field, beyond the usual coupling from...

I thought of posting this under Particle Physics, but it does go slightly beyond standard model, and in a way that could point to some...

Just to be clear, I claimed the problem was that chiral gravi-GUTs want to use SU(2)R as the gravitational gauge group, but in...

the specific model proposed by Stephon Alexander et al, the specific model proposed by Stephon Alexander et al, unified into a single...

A gravi-GUT could be a TOE but wouldn't necessarily be, in the strict sense. A GUT is a unified theory of the three SM forces. A TOE...

so how would you modify the gravi-gut paper by Stephon Alexander et al, to make it work

Formally you could do it but that's not really a gravi-GUT any more, or at least the gravitational SU(2)R is no longer united with the...

could two copies of Pati-Salam gauge group work in providing one SU(2)R for gravity and the second copy SU(2)R reduce to U(1)Y

The standard model gauge group is SU(3) x SU(2)L x U(1)Y. Before the Higgs mechanism comes into play, the latter two subgroups give rise...

could the U(1)Y hypercharge of the standard model perhaps be tied to the Immirizi parameter in Ashtekar gravity, or perhaps be a chiral...

Gravi-GUT theories turn out to play a major role in the alternative physics of the past several decades. E8 theory by Garrett Lisi...

@kodama, I recommend taking a look at this paper from 2017: K. Krasnov & R. Percacci, Gravity and Unification: A review...

this thread is to open up discussion on Gravi-GUT as theories of everything GUT or Grand Unified Theories attempt to unify the 3 forces...

so any cosmologists here can explain the status of quantum cosmology, and its leading candidates?

Since this question is a day old and noone answered you’re gonna get a hack answer: It’s a diverse field. There’s as you you’ve...
