Detailed Description

The main scalar class of KF Particle package, describes particle objects.

Author

Date

Version
1.0

The main scalar class of KF Particle pacakge, describes particle objects. The particle is described with the state vector { X, Y, Z, Px, Py, Pz, E } and the corresponding covariance matrix. It contains functionality to create particle-object from track, to construct short-lived particles from other tracks or particles. The mathematics is based on the Kalman filter method. It also allows to subtract particles from the already constructed object, to transport particles, get parameters together with their errors, get distance to other particles and vertices, get deviations from them in terms of errors, etc.

Member Function Documentation

void KFParticle::AddDaughter ( const KFParticle &  Daughter)
inline

Adds daughter to the current particle. Depending on the selected construction method uses:
1) Either simplifyed fast mathematics which consideres momentum and energy as independent variables and thus ignores constraint on the fixed mass (fConstructMethod = 0). In this case the mass of the daughter particle can be corrupted when the constructed vertex is added as the measurement and the mass of the output short-lived particle can become unphysical - smaller then the threshold. Implemented in the AddDaughterWithEnergyFit() function
2) Or slower but correct mathematics which requires that the masses of daughter particles stays fixed in the construction process (fConstructMethod = 2). Implemented in the AddDaughterWithEnergyFitMC() function.

Parameters
[in]Daughter- the daughter particle

void KFParticle::GetDStoParticle ( const KFParticleBase &  p,
float  dS[2],
float  dsdr[4][6]

inlinevirtual

Virtual method to get extrapolation parameter dS=l/p to another particle. Is defined in KFParticle.

Calculates dS = l/p parameters for two particles, where
1) l - signed distance to the DCA point with the other particle;
2) p - momentum of the particle
dS[0] is the transport parameter for the current particle, dS[1] - for the particle "p". Also calculates partial derivatives dsdr of the parameters dS[0] and dS[1] over the state vectors of the particles:
1) dsdr[0][6] = d(dS[0])/d(param1);
2) dsdr[1][6] = d(dS[0])/d(param2);
3) dsdr[2][6] = d(dS[1])/d(param1);
4) dsdr[3][6] = d(dS[1])/d(param2);
where param1 are parameters of the current particle fP and param2 are parameters of the second particle p.fP. If "HomogeneousField" is defined KFParticleBase::GetDStoParticleBz() is called, if "NonhomogeneousField" is defined - KFParticleBase::GetDStoParticleCBM()

Parameters
[in]p- second particle
[out]dS[2]- transport parameters dS for the current particle (dS[0]) and the second particle "p" (dS[1])
[out]dsdr[4][6]- partial derivatives of the parameters dS[0] and dS[1] over the state vectors of the both particles

) const
inline

Transports the parameters and their covariance matrix of the current particle on a length defined by the transport parameter dS = l/p, where l is the signed distance and p is the momentum of the current particle. If "HomogeneousField" is defined KFParticleBase::TransportBz() is called, if "NonhomogeneousField" - KFParticleBase::TransportCBM(). The obtained parameters and covariance matrix are stored to the arrays P and C respectively. P and C can be set to the parameters fP and covariance matrix fC of the current particle. In this case the particle parameters will be modified. Dependence of the transport parameter dS on the state vector of the current particle is taken into account in the covariance matrix using partial derivatives dsdr = d(dS)/d(fP). If a pointer to F is initialised the transport jacobian F = d(fP new)/d(fP old) is stored. Since dS can depend on the state vector r1 of other particle or vertex, the corelation matrix F1 = d(fP new)/d(r1) can be optionally calculated if a pointer F1 is provided. Parameters F and F1 should be either both initialised or both set to null pointer.

Parameters
[in]dS- transport parameter which defines the distance to which particle should be transported
[in]dsdr[6]= ds/dr - partial derivatives of the parameter dS over the state vector of the current particle
[out]P[8]- array, where transported parameters should be stored
[out]C[36]- array, where transported covariance matrix (8x8) should be stored in the lower triangular form
[in]dsdr1[6]= ds/dr - partial derivatives of the parameter dS over the state vector of another particle or vertex
[out]F[36]- optional parameter, transport jacobian, 6x6 matrix F = d(fP new)/d(fP old)
[out]F1[36]- optional parameter, corelation 6x6 matrix betweeen the current particle and particle or vertex with the state vector r1, to which the current particle is being transported, F1 = d(fP new)/d(r1)
