Which of the following decay processes is allowed by all conservation laws?

Consider the cross-sections σ1 = σ(p + n → Δ+ + n) and σ2 = σ(p + n → Δ0 + p) where (Δ+, Δ0) are part of the baryon decuplet. Then:

The term 'antiprotons', recently seen in the news, is best described as:

Consider the following statements regarding subatomic particles identified at the Large Hadron Collider (LHC): I. The Xi-cc-plus (Ξcc+) particle consists of two 'up' quarks and one 'down' quark, similar to a proton. II. The study of doubly charmed baryons like Xi-cc-plus helps in understanding quantum chromodynamics and the strong force that binds quarks. Which of the statements given above is/are correct?
