Status of Belle II Software
• Munich (Andreas Moll et al.):– First PXD/SVD simulation studies, using Mokka + Marlin;– Optimization studies for the PXD parameters.
• Vienna (Rudi Frühwirth & Moritz Nadler):– Material budget measurements by the “alignment method”;– Feasible only for the CDC, not for PXD/SVD.
• Vienna (Wolfgang Waltenberger):– Vertex Reconstruction Toolkit (RAVE): embedded in Marlin;– New: Gaussian Sum Filter (tested standalone).
• Vienna (Manfred Valentan):– Fastsim tool (LiC Detector Toy): upgrade needed for Belle.

Plans for Belle II Tracking (1)
• New Track Reconstruction:– Module to be embedded in the new Basf2 framework;– Development to be based on the GENFIT skeleton;– Collaboration Vienna – Munich (Christian Höppner et al.).
• Expect from the CDC team:– Standalone PR (e.g. resolving left-right ambiguities)
like old TRASAN + first track fit in CDC;
– Cheater option (passing MC truth) for test purposes. • Development Phase 1:
– Augment GENFIT (DAF, GSF, inclined SVD plaques);– Use inwards extrapolated CDC tracks, add PXD/SVD;– “PR and Precision Track Fit” based on the DAF.

Plans for Belle II Tracking (2)
• Development Phase 2:– Standalone processing of PXD and SVD measurements;– “Pattern Recognition” part based on alternative methods;– “Precision Track Fit” part based on the DAF.
• Development Phase 3 (later):– Outwards extrapolation of standalone PXD/SVD tracks;– Search for and add orphan CDC hits by the DAF.
• New SVD Simulation:– Geometry data base: Vienna (Immanuel Gfall) ;– Digitizations: Prague (Zbynek Drasal);– Suggest a closer collaboration Vienna – Prague.

Plans for Belle II Goodies
• RAVE Vertex Reconstruction:– Toolkit planned be ported to the new Basf2 framework;– Requires new “glue code” (like marlinrave) to cope with
the event model (undergraduate student job ?);– RAVE’s kinematic fit performance is still to be evaluated
against the hard requirements of Belle II physics.
• “LiC Detector Toy” (LDT):– Fastsim tool, used so far for optimization of ILC detectors;– If to be used for Belle II, an upgrade of the detector model
would be needed (undergraduate student job ?).
• Next Tracking Workshop:– Munich, July 15 – 16 ?
