Number of baryons in the Skyrme model
In QCD, the Eightfold Way organizes the number of baryons with respect to their flavor and color quantum numbers: for three light $(u,d,s)$ quark constituents, a spin-(1/2) baryon octet and a spin-(3/...

’t Hooft anomaly matching and massless baryons
In Lectures on Gauge Theory by David Tong there is statement (section 5.6.3 The Vafa-Witten-Weingarten Theorems), that:
To invoke the full power of ’t Hooft anomaly matching, we needed to assume that ...

Spin of skyrmion
Baryons can be considered as solitions in Skyrme model(See also this post.):
Such Lagrangian haven't any information about number of colors. Bosonic or fermionic nature of baryons depends on number ...

Which force is responsible for $\Sigma$(1385) decay?
I was looking at the excited state of the $\Sigma^+$, the $\Sigma^{*+}(1385)$, on Wikipedia. I was wondering which forces are responsible for its two most dominant decays
$$ \Sigma^{*+}(1385) \to \...

Spinor index contractions for baryons
For an $SU(N)$ QCD with $N_f$ flavours one writes baryons as
\begin{equation}
B^{{a_1}…a_{{N}_f}}=\epsilon^{i_1…i_N}\psi_{i_1}^{a_1}… \psi_{i_N}^{a_{Ν_f}}
\end{equation}
by contracting the colour ...

B violation and electric charge
Within SM you can prove that despite we have baryon number conservation respect to Noether theorem, at quantum level baryon (and lepton) number is violated as
$$
\Delta B = 3·\Delta n_{CS}, \quad n_{...
