PDF implementing the generalized Asymmetrical Double-Sided Crystall Ball line shape.

\[ f(m;m_0,\sigma,\alpha_L,n_L,\alpha_R,n_R) = \begin{cases} A_L \cdot (B_L - \frac{m - m_0}{\sigma_L})^{-n_L}, & \mbox{for }\frac{m - m_0}{\sigma_L} < -\alpha_L \\ \exp \left( - \frac{1}{2} \cdot \left[ \frac{m - m_0}{\sigma_L} \right]^2 \right), & \mbox{for }\frac{m - m_0}{\sigma_L} \leq 0 \\ \exp \left( - \frac{1}{2} \cdot \left[ \frac{m - m_0}{\sigma_R} \right]^2 \right), & \mbox{for }\frac{m - m_0}{\sigma_R} \leq \alpha_R \\ A_R \cdot (B_R + \frac{m - m_0}{\sigma_R})^{-n_R}, & \mbox{otherwise}, \\ \end{cases} \]

times some normalization factor, where

\[ \begin{align} A_i &= \left(\frac{n_i}{\left| \alpha_i \right|}\right)^{n_i} \cdot \exp\left(- \frac {\left| \alpha_i \right|^2}{2}\right) \\ B_i &= \frac{n_i}{\left| \alpha_i \right|} - \left| \alpha_i \right| \\ \end{align} \]

Member Function Documentation

◆ analyticalIntegral()

double RooCrystalBall::analyticalIntegral ( Int_t  code,
const char *  rangeName = 0 
) const
overridevirtual

Implements the actual analytical integral(s) advertised by getAnalyticalIntegral.

This functions will only be called with codes returned by getAnalyticalIntegral, except code zero.

Reimplemented from RooAbsReal.

Definition at line 242 of file RooCrystalBall.cxx.

◆ Class()

static TClass * RooCrystalBall::Class ( )

Definition at line 52 of file RooCrystalBall.h.

◆ evaluate()

double RooCrystalBall::evaluate ( ) const
overrideprotectedvirtual

Evaluate this PDF / function / constant. Needs to be overridden by all derived classes.

Implements RooAbsReal.

Definition at line 204 of file RooCrystalBall.cxx.

◆ getAnalyticalIntegral()

Int_t RooCrystalBall::getAnalyticalIntegral ( RooArgSet allVars,
RooArgSet analVars,
const char *  rangeName = 0 
) const
overridevirtual

Interface function getAnalyticalIntergral advertises the analytical integrals that are supported.

'integSet' is the set of dependents for which integration is requested. The function should copy the subset of dependents it can analytically integrate to anaIntSet and return a unique identification code for this integration configuration. If no integration can be performed, zero should be returned.
