Is there anything else that the neutron does other than saveing the conservation laws. i mean there has to be something else the neutron plays a part of in the universe.

What does the bottom quark do for the universe? This is not a sensible question.

Neutron or neutrino? The neutron is responsible for stabilizing atoms to allow multiproton atoms to form, whereas neutrinos teach us astronomy :smile: - actually they might be responsible for some more CP violation, but we don't know yet since it's so hard to make any measurements with them.
 
Well, neutrinos were at first brought into physics just to save conservation laws of energy and momentum in beta decays. But later they have also been detected, so I do not see a point of this discussion? O_o

Well, another thing that neutrinoes could partly solve, is the problem of dark matter. If they had a tiny mass (as expected nowadays) they could be the hot dark matter. Cold dark matter is still a big question, as well as origin of neutrino masses. :|
 
Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...
I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
