Please teach me this:
Does ''Higgs sector'' mean there are many Higgs particle types?Does custodial SU(2) symmetry using mean maybe there is a theory of electroweak interaction more complex than theory of single Higgs scalar?
Thank you in advance.
 
Physics news on Phys.org
I mean there may be many type of Higgs boson in the theory of electroweak interaction because they say '' Higgs sector''.
 
There are models with multiple Higgs bosons (most notably supersymmetry), but I heard the term "Higgs sector" for the model with just one Higgs particle, too. The model of EW symmetry breaking is complex enough to call that part "Higgs sector".
 
Please tell me more some details of the role of custodial symmetry(SU(2)) in Standard Model extent.
 
If you look for an introduction to the Higgs mechanism, read a book or lecture script.
 

Thread 'Gravitational self-interaction: another attempt to replace Dark Matter'

https://arxiv.org/pdf/2503.09804 From the abstract: ... Our derivation uses both EE and the Newtonian approximation of EE in Part I, to describe semi-classically in Part II the advection of DM, created at the level of the universe, into galaxies and clusters thereof. This advection happens proportional with their own classically generated gravitational field g, due to self-interaction of the gravitational field. It is based on the universal formula ρD =λgg′2 for the densityρ D of DM...

Thread 'Twistors and celestial holography'

Many of us have heard of "twistors", arguably Roger Penrose's biggest contribution to theoretical physics. Twistor space is a space which maps nonlocally onto physical space-time; in particular, lightlike structures in space-time, like null lines and light cones, become much more "local" in twistor space. For various reasons, Penrose thought that twistor space was possibly a more fundamental arena for theoretical physics than space-time, and for many years he and a hardy band of mostly...
