Predicting the positive parity and zero spin of the Higgs boson?

In summary, researchers have been able to predict the positive parity and zero spin of the Higgs boson, a subatomic particle that plays a crucial role in the Standard Model of particle physics. This was achieved through experiments and analyses at the Large Hadron Collider, where the Higgs boson was discovered in 2012. These findings provide further evidence for the existence of this elusive particle and help to deepen our understanding of the fundamental forces and particles that make up our universe.

Can we predict the positive parity, and zero spin of the Higgs boson from the decay mode: 𝐻 → 𝛾𝛾?

##H\to \gamma\gamma## tells you that it is not spin-1, because that decay is forbidden by the Landau-Yang theorem.

I think the mere existence of that decay channel does not exclude anything else for spin and parity, without more detailed analyses of the decays.

This paper (https://arxiv.org/pdf/1506.05669.pdf) is using ##H\to \gamma\gamma## to study the spin-2 hypothesis (but they also use other channels), but it does not seem to be sensitive to the pseudo-scalar hypothesis.

Do we expect that parity and spin are conserved in this particular decay? If so can we use the spin and parity of the two photons to predict those for the H boson?

ATLAS and CMS wrote multiple papers about that. Did you read them?

Predicting the positive parity and zero spin of the Higgs boson is important because it helps us better understand the fundamental building blocks of the universe. These predictions can also be compared to experimental data to confirm the existence of the Higgs boson and validate our current theories about the nature of matter and energy.

3. How accurate are these predictions about the Higgs boson's spin and parity?

The predictions about the Higgs boson's spin and parity are based on the best available scientific knowledge and data, but they are not 100% certain. As with any scientific theory, there is always room for further experimentation and refinement. However, the predictions have been confirmed by experiments at the Large Hadron Collider, giving scientists confidence in their accuracy.
