Hello,
I have read somewhere that the Higgs Boson particle (or field) is responsible for the inflation of the universe. Does anybody have more information?
Thanks.

google "higgs inflation" to find some theories which probe this theoretical space

"I have read somewhere" gives us no guidance on what it is that you have read or where can we find it. "I have read something somewhere, but won't tell you where or exactly what, but want more" is an impossible question to answer.
 
There are some ideas how the Higgs mechanism (but not the particle) could be related to inflation, a phase of very rapid expansion of the very early universe. It is unclear if these ideas are correct, and I don't see how a [b]-level thread could go into details.
 
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}...
