First Experimental Determination Of Proton Weak Charge Determined

Researchers are reporting the first experimental determination of the weak charge of the proton, one of the four fundamental forces in our universe, along with gravity, electromagnetism and the strong force. Although the weak force acts only on the sub-atomic level, we can see its effects in our everyday world. The weak force plays a key role in the nuclear reaction processes that take place in stars and is responsible for much of the natural radiation present in our universe.  read more
