They are ridiculously hard to come by. However, at EMU, we’re fortunate enough to have a Bifurcated Trandelammer (donated by the late Zebulon Pratik), which allows us to have the largest gluon accelerator in the country.
I think I understood about 1/2 of that, now if you would be so kind to explain what gluon refractometry. is, that would help a lot. I think I know what gluon is, It's something that holds subatomic particles together isn't it?
