Find the strangeness S and the hypercharge Y of a neutral elementry particle whose isotopic spin projection is T_(z)= +1//2 and baryon charge B= +1. What particle is this.

Answer»

Solution :From the Gell-Mann Nishijama formula
`Q=T_(Ƶ)+(Y)/(2)`
we GET `O=(1)/(2)+(Y)/(2) or Y=-1`
ALSO `Y=B+Simplies S-2`. THUS the PARTICLE is `=^(o)0`
