Detailed Description

Common base class to all track types, including Muon fits. Internally, the following information is stored:

A reference position on the track: (vx,vy,vz)

Momentum at this given reference point on track: (px,py,pz)

5D curvilinear covariance matrix from the track fit

Charge

Chi-square and number of degrees of freedom

Summary information of the hit pattern

For tracks reconstructed in the CMS Tracker, the reference position is the point of closest approach to the centre of CMS. For muons, this is not necessarily true.

Parameters associated to the 5D curvilinear covariance matrix:
(qoverp, lambda, phi, dxy, dsz)
defined as:

qoverp = q / abs(p) = signed inverse of momentum [1/GeV]

lambda = pi/2 - polar angle at the given point

phi = azimuth angle at the given point

dxy = -vx*sin(phi) + vy*cos(phi) [cm]

dsz = vz*cos(lambda) - (vx*cos(phi)+vy*sin(phi))*sin(lambda) [cm]

Geometrically, dxy is the signed distance in the XY plane between the the straight line passing through (vx,vy) with azimuthal angle phi and the point (0,0).
The dsz parameter is the signed distance in the SZ plane between the the straight line passing through (vx,vy,vz) with angles (phi, lambda) and the point (s=0,z=0). The S axis is defined by the projection of the straight line onto the XY plane. The convention is to assign the S coordinate for (vx,vy) as the value vx*cos(phi)+vy*sin(phi). This value is zero when (vx,vy) is the point of minimum transverse distance to (0,0).

Note that dxy and dsz provide sensible estimates of the distance from the true particle trajectory to (0,0,0) ONLY in two cases:

When (vx,vy,vz) already correspond to the point of minimum transverse distance to (0,0,0) or is close to it (so that the differences between considering the exact trajectory or a straight line in this range are negligible). This is usually true for Tracker tracks.

When the track has infinite or extremely high momentum

More details about this parametrization are provided in the following document:
