Can you tell wavefunction's chirality by looking at it?
I recently learned, that:
Helicity is a combination of particle's "rotation"
(Spin) and direction of it's motion.
The motion is relativity-dependant, and so is helicity.
Chirality ...

Is CPT symmetry a direct consequence of Special Relativity?
I'm wondering about the origin of $\mathcal{CPT}$ symmetry in the Standard Model. The Wikipedia entrance makes me understand it is a direct consequence of Special Relativity. Is it right?

Why is the Higgs $CP$ even?
Why was it always assumed that the Higgs boson is a CP even particle?
I understand that experimentally, it just is so but I am under the impression that before its discovery people took it to be CP ...

Does the weak force obey the CPT symmetry? How?
I have read that the weak force does not obey the charge symmetry, the parity symmetry, and the time reversal symmetry.
Then how does it obey the CPT symmetry?

chiral symmetry condensate and 2SC, CFL breaking C, P and T symmetry?
Because we know that chiral symmetry condensate causes the chiral symmetry breaking, and it produces Goldstone modes of pseudo-scalars, so I believe that chiral symmetry breaking also breaks the T ...

Conservation of $C$-Parity and $P$-parity
Under what situations are $C$-Parity $C=(-1)^{L+S}$ and/or $P$-parity $P=-(-1)^L$ conserved? ( $L$ here is the relative angular momentum and S is the total intrinsic spin).
It would make sense that ...

Does the Higgs mechanism address the spin statistics problem?
Since the Higgs mechanism is so intimately tied to binding together massless chiral fermions, does it happen to have anything to say about the spin statistics issue?
I'm actually assuming the answer ...

Do any good theories exist on why the weak interaction is so profoundly chiral?
I find the profound asymmetry in the sensitivity of left and right chiral particles to be one of the most remarkable analytical observations captured in the Standard Model. Yet for some, I've not ...
