String Theory & Higgs: Explaining Spin 0

[Chewy0087]

Don't really want to go into much detail here :P, was just wondering during a crappy elctro/physics lesson today;

I find it hard to understand the concept of spin at all in string theory, but assuming it's the same as the standard model (it's physically spinning) as opposed to vibrating or something, and assuming that the Higgs does have spin 0, how would that be explained/pictured? ;p

I presume then that the string will not be curled up in a ball as it is imagined to be in protons etc, but instead is unfurled (a straight string), and not vibrating at all? I'd really like to understand it, or at least get an idea in my mind to picture ;p, string theory is awesome

Thanks yous
merci en avance

"Spin" actually has to do with the specific SO(3,1) representation that a particle lives in. After compactification, string theory can give the needed representations of SO(3,1).

I can understand your confusion and curiosity about the concept of spin in string theory and how it relates to the Higgs field. Spin is a fundamental property of particles and is often described as the intrinsic angular momentum of a particle. In the standard model of particle physics, spin is described as a physical spinning motion of the particle.

In string theory, however, spin is not described in terms of physical spinning, but rather as a mathematical property of the string itself. The string is considered to be one-dimensional, meaning it has length but no width or height. This allows it to vibrate in different modes, which correspond to different particles in the standard model.

Now, in terms of the Higgs field, it is believed to have a spin of 0. This means that it does not have any physical spinning motion, but rather a scalar field that permeates all of space. This field is responsible for giving particles their mass through the Higgs mechanism.

To try and explain this concept in a more visual way, you can imagine the string in string theory as a straight, unfurled string rather than a curled up ball. And the Higgs field can be visualized as a field of energy that fills all of space, giving particles their mass.

I hope this helps to give you a better understanding of spin in string theory and its relationship to the Higgs field. Keep exploring and learning about string theory, it truly is an amazing and fascinating area of study.
