Here are a few numbers
Here are a few numbers

  • I(spectrum; range) is the integral of any spectrum over an specific range..

  • N is a numerical factor that often (but not always) results from the ratio of various integrals. On the following slides is what I believe that both Ermias and Mihael did.


Ermias
Ermias

  • N++ = I(FG++,non-jet) / I(BG++, non-jet)

  • N-- = I(FG--, non-jet)/I(BG--,non-jet)

  • Nermias = SQRT(N++N--)

  • Background = Spectrum(BG+-) * Nermias


Mihael
Mihael

  • N++ = I(FG++,high mass)/I(BG++, high mass)

  • N-- = I(FG--, high mass)/I(BG--, high mass)

  • I++ = N++ * I(BG++,WHOLE SPACE)

  • I-- = N-- * I(BG--,WHOLESPACE)

  • F = 2*SQRT(I++ *I--)/I(BG+-,WHOLESPACE)

  • Background = F * Spectrum(BG+-)
