Question 16 (10 marks) A particle consisting of four quarks and one anti-quark is called a pentaquark. Pentaquarks were theorised as early as 1964 and the first evidence of their existence obtained in 2003. However, it wasn't until 2015 (and again in 2019) that enough data had been gathered to make a genuine claim that a particle had been discovered that matched the theoretical properties of a pentaquark. (a) Show, via a calculation, that a pentaquark has a baryon number of +1. (2 marks) b) The equation below describes the formation of a pentaquark. A lambda baryon, Ag (bud) decays via a W- boson, forming a kaon minus, K- (su) and the pentaquark, Pat (uccud). 18 - K- + Pc# i. State which fundamental force is responsible for mediating this decay. Justify your choice. (2 marks) Force: Justification: ii. Mesons are particles consisting of a quark and an antiquark. State the names of the fundamental particles of the meson in the decay reaction. (2 marks) SEE NEXT PAGE Physics Units 3 & 4 15 ili. Show that electric charge is conserved during this decay. (2 marks) iv. Show that baryon number is conserved during this decay. (2 marks)
