Just a quick question. I thought formulation of loop structure was based on the idea using Giles's theorem and defining different colors via dimensions of solution to the connection's algebra. Here, the author says it's due to vibrations as in QFT. Thoughts?

Aha, there we go. Thanks a lot pwsnafu for the verification! as well as others for your time generous reply.

@micromass, @pwsnafu, I see what you are saying. Overall, you have convinced me {ℝ} is possible. But, The notation with curly bracket is directly defining the single element in this set as the real space which is essentially another set. I was simply saying there is no necessity to put real...

Thanks bjunniii, you have a good point. However, let me rephrase my doubt. We want to use a notation to represent a set of all real number, say X. It is immediately apparent that x \in X \subseteq ℝ for some real number x. In this case, we are not not considering any stronger set, for...

What is {ℝ}? Hi, Someone I know tried to convey me the meaning of {ℝ}, stating it represents a set of real numbers. But using notation, {ℝ}, is implying that the real space is (improperly) contained in a set, and I don't think this makes any logical sense. On the other hand, we can say {x...

I am not so sure all baryon decay weakly. First, consider the classical example of positive pions scattering with protons which can produce neutral lambdas. Then, for instance, it has been experimentally proven that such lambda can decay strongly b/c we can trace its track within reasonable...

I think it's also possible to look at the quark content of the neutrons and proton; if they are really confined such that you have to pick one or the other using Pauli's exclusion principle, you can have different colors of quarks which validates the statement of how proton and neutron can...

mfb, it does make whole lot more sense now; thanks a lot btw Vanadium 50, (correct me if I'm wrong) you don't need a particle decay to be in CP eigenstate to conserve charge conjugation/parity in any non-weak interactions.

Vanadium 50, it's probably because of some CP conservation; so we have pions as products. This is why the intermediate photons are only virtual and we need quarks to be produced.

Yea, I see how this works like that. But as I mentioned before, since 'positive pion + negative pion' can be produced through two photons why wouldn't it be produced more often than the ones from weak interaction? Also a stupid question, when do you take the Vxx to be negative? Vxx = any...

Hi all, I have a question regarding to the branching ratio of neutral D-meson decay. Give three decays: 1. D --> negative kaon + positive pion 2. D --> positive pion + negative pion 3. D --> positive kaon + negative pion The one with highest branching ratio is 1. due to its non-cross...

Hi all, I was wondering, is this scattering process even possible? Since we cannot mix the two neutrinos on one side due to lepton number conservation, we need to convert one of the neutrino to its anti-neutrino by crossing symmetry. To conserve tau&mu number we have: tau-neutrino + anti...

So you are implying all time-independent ones do? including the non-normalizable ones

Hi all, This may seem silly but...do energy eigenstates always exist in terms of wave functions themselves? To me, it seems they do because they always contain quantized energies. How about any hypothetical non-normalizeable wave functions? Thanks O.

Thanks a lot! It really helps
