Hi Ming,

Yes, so far I only used 1 INTT layer to discriminate against out-of-time events. We certainly should reconstruct tracks using 2 MVTX hit + (2+) INTT hits at next iteration, but 2 MVTX hits only won't provide good starting curvature (for phi segmentation) or z0 parameter (for z segmentation) for INTT, thus cannot be used for in-time vertexing. I did not apply any pT cut on tracks used for vertexing.

Best regards,

Sookhyun

Hi Sookhyun,
Nice work! So in your analysis, only one INTT hit was used to tag in-time association to a MVTX triplets? How about if you only use MVTX tracklet with two hits only? Have you applied any minimum momentum cuts?

Cheers
Ming

Let us have discussions tomorrow at Inner tracking task force meeting as well.

Best regards,
