889  // NB THe following block of explanations for background models is outdated, see detailed
890  // explanations where the code computes PB.
891  // +++++++++++++++++++++++
892  // For the background, instead, we have two choices: a linear and an exponential model.
893  // * For the linear model, we choose a one-parameter form whereby the line is automatically normalized
894  // in the support [x1,x2] where we defined our "signal region", as follows:
895  //
896  // B(x;b) = 1/(x2-x1) + {x - (x2+x1)/2} * b
897  //
898  // Defined as above, B(x) is a line passing for the point of coordinates (x1+x2)/2, 1/(x2-x1),
899  // whose slope b has as support the interval ( -2/[(x1-x2)*(x1+x2)], 2/[(x1-x2)*(x1+x2)] )
900  // so that B(x) is always positive-definite in [x1,x2].
901  //
902  // * For the exponential model, we define B(x;b) as
903  //
904  // B(x;b) = b * { exp(-b*x) / [exp(-b*x1)-exp(-b*x2)] }
905  //
906  // This one-parameter definition is automatically normalized to unity in [x1,x2], with a parameter
907  // b which has to be positive in order for the slope to be negative.
908  // Please note that this model is not useful in most circumstances; a more useful form would be one
909  // which included a linear component.
910  // ++++++++++++++++++++++
911  //
912  // Once GL(m,s) and B(x;b) are defined, we introduce a further parameter a, such that we can have the
913  // likelihood control the relative fraction of signal and background. We first normalize GL(m,s) for
914  // any given s by taking the integral
915  //
916  // Int(x1,x2) GL(m,s) dm = K_s
917  //
918  // We then define the probability as

924  // and the four parameters m,s,a,b fully control its shape.
925  //
926  // It is to be noted that the formulation above requires the computation of two rather time-consuming

We use the following formula:

M = sqrt ( (E1+E2)^2 - (P1+P2)^2 )

where we express E and P as a function of Pt, phi, and theta:

E = sqrt ( Pt^2*(1+cotg(theta)^2) + M_mu^2 )
Px = Pt*cos(phi), Py = Pt*sin(phi), Pz = Pt*cotg(theta)

from which we find

M = sqrt( 2*M_mu^2 + 2*sqrt(Pt1^2/sin(theta1)^2 + M_mu^2)*sqrt(Pt2^2/sin(theta2)^2 + M_mu^2) - 2*Pt1*Pt2* ( cos(phi1-phi2) + cotg(theta1)*cotg(theta2) ) )

and derive WRT Pt1, Pt2, phi1, phi2, theta1, theta2 to get the resolution.

This method can be used outside MuScleFit. It gets the ResolutionFunction that must have been built with the parameters.
TO-DO: this method duplicates the code in the previous method. It should be changed to avoid the duplication.

Computes the probability given the mass, mass resolution and the arrays with the probabilities and the normalizations.

After the introduction of the rapidity bins for the Z the probability method works in the following way:

  • if passing iRes == 0, iY is used to select the rapidity bin
  • if passing iRes != 0, iY is used to select the resonance
