Hi all,

I read one of the CMS results for new charged Higgs on :
https://twiki.cern.ch/twiki/bin/view/CMSPublic/Hig14020TWiki

I can't understand this sentence at the main results:
An expected 95 % CL model-independent upper limit on B(t->bH+) x B(H+ -> tau nu) in the range of 1.1-0.22 % is obtained for m_H+ = 80-160 https://twiki.cern.ch/twiki/bin/view/CMSPublic/GeV while for m_H+ = 180-600 https://twiki.cern.ch/twiki/bin/view/CMSPublic/GeV a model-independent limit on sigma(pp -> H+- tb) is set to 0.41-0.030 pb. The corresponding observed 95 % CL model-independent upper limit is set to 1.2-0.16 % for m_H+ = 80-160 https://twiki.cern.ch/twiki/bin/view/CMSPublic/GeV and to 0.38-0.026 pb for m_H+ = 180-600 https://twiki.cern.ch/twiki/bin/view/CMSPublic/GeV . The results are interpreted in different MSSM benchmark scenarios and are used to set exclusion limits in the m_H+ - tan(beta) and m_A - tan(beta) parameter spaces.

What does it mean? is that constrains the theoretical calculations of sigma(pp -> H+- tb) to be 0.41-0.030 pb,
what about the last sentence which mentions "0.38-0.026 pb" ?

Bests,
S.

The ranges correspond to the mass ranges, different masses have different exclusion limits.
 
Thanx, I got it.
 
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}...
