Question

the excange particles responsible for weak interaction are

Answer 1

Like there are gluons which are the exchange particles responsible for strong interaction , there is a small group of particles called intermediate vector bosons which is responsible for metering out the weak force which is stronger than gravity but is active in very small distances.

Answer 2

The exchange particles for weak interaction come under the category of bosons.

The particles responsible are called
W+, W-, and Z° (Z naught)

The plus, minus, and zero (and not degree) sign are written on the the superscript
