It's pretty easy to understand why Ω and Λ have to decay weakly; Ω has three s quarks so, no other baryon to turn into without changing strangeness. As for Λ, it is the lightest baryon with unit strangeness. But when it comes to, for example, Σ 0 it can decay to Λ + γ.
Do baryons only decay via the weak force? Physics Forums
WebThe final thing I would be interested in: Is there a fundamental reason why one can not have a superposition of different states of charge or strangeness or bottomness? I'm asking, because in atomic physics, an e- can be in different eigenstates of the principal q.number or of angular momentum q.number; photons can be a superposition of ... Particles could be described with isospin projections (related to charge) and strangeness (mass) (see the uds octet and decuplet figures on the right). As other quarks were discovered, new quantum numbers were made to have similar description of udc and udb octets and decuplets.

Spectroscopy of light baryons with strangeness -1, -2, and -3
WebMay 6, 2024 · So a baryon can only reduce the rest mass-energy by the weak force, the strong/EM just increase it for a baryon. ... Strangeness is conserved in the production process, which is strong, and since the Λ 0 has strangeness S = -1, Λ's can only be produced in association with other strange particles, e.g. a K + meson with S = +1. WebThe pion, proton, and neutron have S = 0. Because the strong force conserves strangeness, it can produce strange particles only in pairs, in which the net value of strangeness is zero. This phenomenon, the … flug von frankfurt nach colombo
