// This routine computes the likelihood that a given measured mass "measMass" is
// the result of a reference mass ResMass[] if the resolution
// expected for the two muons is massResol.
// This version includes two parameters (the last two in parval, by default)
// to size up the background fraction and its relative normalization with respect
// to the signal shape.
//
// We model the signal probability with a Lorentz L(M,H) of resonance mass M and natural width H
// convoluted with a gaussian G(m,s) of measured mass m and expected mass resolution s,
// by integrating over the intersection of the supports of L and G (which can be made to coincide with
// the region where L is non-zero, given that H<<s in most cases) the product L(M,H)*G(m,s) dx as follows:
//
// GL(m,s) = Int(M-10H,M+10H) [ L(x-M,H) * G(x-m,s) ] dx
//
// The above convolution is computed numerically by an independent root macro, Probs.C, which outputs
// the values in six 1001x1001 grids, one per resonance.
//
// NB THe following block of explanations for background models is outdated, see detailed
// explanations where the code computes PB.
// +++++++++++++++++++++++
// For the background, instead, we have two choices: a linear and an exponential model.
// * For the linear model, we choose a one-parameter form whereby the line is automatically normalized
// in the support [x1,x2] where we defined our "signal region", as follows:
//
// B(x;b) = 1/(x2-x1) + {x - (x2+x1)/2} * b
//
// Defined as above, B(x) is a line passing for the point of coordinates (x1+x2)/2, 1/(x2-x1),
// whose slope b has as support the interval ( -2/[(x1-x2)*(x1+x2)], 2/[(x1-x2)*(x1+x2)] )
// so that B(x) is always positive-definite in [x1,x2].
//
// * For the exponential model, we define B(x;b) as
//
// B(x;b) = b * { exp(-b*x) / [exp(-b*x1)-exp(-b*x2)] }
//
// This one-parameter definition is automatically normalized to unity in [x1,x2], with a parameter
// b which has to be positive in order for the slope to be negative.
// Please note that this model is not useful in most circumstances; a more useful form would be one
// which included a linear component.
// ++++++++++++++++++++++
//
// Once GL(m,s) and B(x;b) are defined, we introduce a further parameter a, such that we can have the
// likelihood control the relative fraction of signal and background. We first normalize GL(m,s) for
// any given s by taking the integral
//
// Int(x1,x2) GL(m,s) dm = K_s
//
// We then define the probability as
//
// P(m,s,a,b) = GL(m,s)/K_s * a + B(x,b) * (1-a)
//
// with a taking on values in the interval [0,1].
// Defined as above, the probability is well-behaved, in the sense that it has a value between 0 and 1,
// and the four parameters m,s,a,b fully control its shape.
//
// It is to be noted that the formulation above requires the computation of two rather time-consuming
// integrals. The one defining GL(m,s) can be stored in a TH2D and loaded by the constructor from a
// file suitably prepared, and this will save loads of computing time.

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.

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.
