Violation of Newton 3 rd Law

[Verpies]

For example, when a neutron decays into a proton and electron, the new pair of particles don’t fly apart in exactly opposite directions. Instead, the pair have a net momentum that the original neutron did not.
The implication (according to Newton’s law) is that there must be another particle to balance things out.  

And that’s exactly the case.  
Although the “extra particle that’s really hard to detect” 
theory was first proposed in 1930, it wasn’t until 1956 that neutrinos were finally detected and verified to exist.

...or these particles were motion in the first place.

I guess the statement "Instead, the pair have a net momentum that the original neutron did not." is decisive
