Quark model — UPSC CSE 2006 Physics PYQ

(i) Exlain the quark structure of hadrons. Identify the field of quark of electro-weak and electro-strong interactions. Also verify the conservation of strangeness in the following reactions : 10 \pi^- + p \rightarrow \Lambda^\circ + K^\circ K^+ \rightarrow \pi^+ + \pi^+ + \pi^- (ii) Drawing necessary diagrams, explain diamond structure and CsCl structures. 10
