The following reaction can occur by the strong interaction: π⁰ + n → K⁺ + Σ^-.If the quark composition of the n is (udd),the π ⁰ is And the composition of the K⁺ is ,what is the quark composition of the Σ^-? A) uds B) dds C) sss

Question

Quizplus · Accepted Answer

We can determine the quark composition of the Σ^- by comparing the quark compositions of the reactants and products. The quark composition of the neutron (udd) is the same as that of the Σ^-, except that one of the u quarks is replaced by an s quark. Therefore, the Σ^- must have a quark composition of uds. Choice B is the only option that matches this composition.
