A sigma-plus (Σ+) particle and an unidentified particle Y are produced by the strong
interaction between a positive pion (π+) and a proton (p).
This interaction is represented by the equation:
π + + p → Σ+ + Y
0 1 .1
Complete Table 1 to show the baryon number B, charge Q and strangeness S for
the particles in this interaction.
