Addition and convolution: decay function pdfs with optional B physics effects (mixing and CP violation)
that can be analytically convolved with e.g. Gaussian resolution functions
pdf1 = decay(t,tau) (
x) delta(t)
pdf2 = decay(t,tau) (
x) gauss(t,
m,s)
pdf3 = decay(t,tau) (
x) (
f*gauss1(t,m1,
s1) + (1-
f)*gauss2(t,m1,
s1))

RooAddModel is an efficient implementation of a sum of PDFs of the form.
RooArgList is a container object that can hold multiple RooAbsArg objects.
Single or double sided decay function that can be analytically convolved with any RooResolutionModel ...
Class RooGaussModel implements a RooResolutionModel that models a Gaussian distribution.
Plot frame and a container for graphics objects within that frame.
static RooPlot * frame(const RooAbsRealLValue &var, double xmin, double xmax, Int_t nBins)
Create a new frame for a given variable in x.
void Draw(Option_t *options=nullptr) override
Draw this plot and all of the elements it contains.
Variable that can be changed from the outside.
Implements a RooResolution model that corresponds to a delta function.
virtual void SetTitleOffset(Float_t offset=1)
Set distance between the axis and the axis title.
The namespace RooFit contains mostly switches that change the behaviour of functions of PDFs (or othe...
