DATABASE INCLUDES.

Name : Neutrino.h Package : offline/PhysicsAnalysis/AnalysisCommon/ParticleEvent Author : Ketevi A.

An example algorithm that reads and writes objects from the event store using handles.

A tool to be used for track preselection in conversion vertex finding.

Forward declarations.

The InDetV0FinderTool reads in the TrackParticle container from StoreGate, if useorigin = True only tracks not associated to a primary vertex are used.

There are options to use silicon tracks only (default) or include Si+TRT and TRT+TRT.

Pairs of tracks passing pre-selection (using InDetTrackSelectorTool) are fitted to a common vertex using TrkV0Fitter or TrkVKalVrtFitter (useV0Fitter = False).

InDetV0FinderTool can take as input a vertex (or a collection of vertices) w.r.t which the V0s can be selected to minimise combinatorics.

• if such a vertex is provided, tracks are used if fabs(d0/sig_d0) > d0_cut (= 2.)
• if useVertexCollection = True all vertices in the collection are used
• if useVertexCollection = False
  • if trkSelPV = True either a primary vertex, if provided, or the beam spot are used
  • if trkSelPV = False (default) all track combinations are used.

The unconstrained vertex fit is attempted if the radius of the starting point is < maxsxy (= 1000 mm) and at least one invariant mass at the starting point is in the allowed range: uksmin < m(pipi) < uksmax or ulamin < m(ppi) < ulamax or ulamin < m(pip) < ulamax

V0s are kept if the cumulative chi2 probability of the unconstrained fit is > minVertProb (= 0.0001)

If doSimpleV0 = True all vertices that pass these cuts are stored in V0UnconstrVertices.

If doSimpleV0 = False (default) mass constrained fits are attempted if

• the invariant mass of the unconstrained V0 is in the allowed range: ksmin < m(pipi) < ksmax, lamin < m(ppi), m(pip) < lamax and the error on the invariant mass is < errmass (= 100 MeV)
• if an input vertex (collection) is provided the unconstrained V0 is required to have an impact parameter w.r.t the vertex < vert_a0xy_cut (= 3 mm) in xy and < vert_a0z_cut (= 15 mm) in z, the cosine of the angle between the V0 momentum and the direction from the input vertex to the V0 vertex is > 0, Lxy w.r.t the vertex is < vert_lxy_cut (= 500 mm) and Lxy/sigma(Lxy) > vert_lxy_sig (= 2)

Mass constrainedV0s are kept if the cumulative chi2 probability of the fit is > minVertProb (= 0.0001)

For successful mass constrained fits a conversion fit is also attempted and if successful, the corresponding unconstrained V0 is decorated with the invariant mass, its error and the vertex probability of the conversion fit.

The links between the unconstrained V0 and the successful mass constrained V0s are stored.

The AlignTracks are filled into a collection of Tracks. The default control flow is like this: firstly do vertex constraint, if can't, then do beamspot again; if can't again, then do normal refit. if want to do vertex constraint only, set: doVertexConstraint = True and doBeamspotConstraint = False if want to do beamspot constraint only, set: doVertexConstraint = False and doBeamspotConstraint = True

Will provide a track coolection with momentum conatraint applied. A 2d histogram read and corrections (delta) are extracted as function of eta and phi. The momentum is scaled as corrected QoverP = original QoverP * (1.+ charge *pt *delta );

The strength of eth constraint can be varied as well.

instead of the CaloCell_ID (enum) a simple int is taken, so, implicit conversion is needed.

pos/neg endcap are distinguished by +/-

In the case of surfaces we do not want to take onwership when they are owned by the Tracking Geometry or a detector element.

In the other hand we want to take ownership if they are free.

As a result when we have classes with a m_associatedSurface member we need to repeat some boiler plate code.

These helpers try to make writing such code a bit easier and more uniform.

In reality one should prefer the code based on SurfaceUniquePtr But : We get this kind of warning when creating dictionaries: Error in <CloseStreamerInfoROOTFile>: I/O is supported only for unique_ptrs with a default deleter. Trk::SurfaceUniqHolder::m_associatedSurface appears to have a custom one Which can be problematic for some cases. So we provide also the plain ptr one

Under TrkDetDescr/TrkSurfaces :

The test : SurfaceHolder_test has a mock code on how we could use these for classes where we want to hold a ptr to a const Surface and manage it, based on if its free or owned.

The header : SurfaceHolder.h provides typedefs for most commom cases used by client code so as to hide some details of the implementation

propJacobian()

ATH_ALWAYS_INLINE void Trk::propJacobian	(	double *ATH_RESTRICT	P,
		const double *ATH_RESTRICT	H0,
		const double *ATH_RESTRICT	H1,
		const double *ATH_RESTRICT	H2,
		const double *ATH_RESTRICT	A,

		const double *ATH_RESTRICT	A3,
		const double *ATH_RESTRICT	A4,
		const double *ATH_RESTRICT	A6,
		const double	S3
	)

This provides an inline helper function for updating the jacobian during Runge-Kutta propagation.

Used in several clients, put in here to avoid code duplication Based on the existing implementation, but using vectorisation to improve speed by approximately 30%.

The mathematics behind this procedure are documented in JINST 4 (2009) P04016 also found as http://cds.cern.ch/record/1114177 / https://inspirehep.net/literature/826186

In this implementation, we preserve the conventions of client code, hence the use of array pointers rather than std constructs. P is a 42-element array containing global coordinates, direction, inverse momentum and Jacobian of transformation. Its elements are updated in-place by this method. H0, H1, and H3 represent the field at the three points eachj is a 3-element array A represents the direction vector before propagation It is a 3-vector A0, A3, A4, and A6 represent cross products of the direction with the field across the 3 points. Each is a 3-vector. S3 is a step length

now update the parameter array in the slots representing the Jacobian
