[Eic-core-phys] CORE Silicon Tracking - Reinforcement

[Hugh Montgomery]

Charles, Pawel et al,

It turns out that a friend of mine, Ashutosh Kotwal from DUKE had (this past Fall) sent me some information on some of his ideas for tracking high multiplicities in silicon detectors. I only this past couple of days got around to reading his NIM paper. It seems to me that it justifies your/our claim that the 6 layer CORE silicon tracker will find the tracks we seek. The environment he postulates is that of HL-LHC. I think that the EIC environment is relatively benign in comparison to HL-LHC.

Ashutosh refers to the paper which I have read an idealized version which was published in NIM.

He says that here is another paper in the works, describing an integrated circuit implementation. It will prove that the concept actually works.

Ashutosh's real aim is to seek and find disappearing tracks (indicating decays involving Dark Matter) and he points to:
" ....  a solution for the problem of track triggering at the LHC. See

This paper describes a more advanced algorithm under realistic conditions. "
