An extension of the Gluckstern formulas for multiple scattering: analytic expressions for track parameter resolution using optimum weights

Momentum, track angle and impact parameter resolution are key performance parameters that tracking detectors are optimised for. This report presents analytic expressions for the resolution of these parameters for equal and equidistant tracking layers. The expressions for the contribution from position resolution are based on the Gluckstern formulas and are well established. The expressions for the contribution from multiple scattering using optimum weights are discussed in detail

Status & Challenges of Tracker Design for FCC-hh

A 100 TeV proton collider represents a core aspect of the Future Circular Collider (FCC) study. An integral part of this project is the conceptual design of individual detector systems that can be operated under luminosities up to $3\times10^{35} \mathrm{cm}^{-2} \mathrm{s}^{-1}$. Compared to HL-LHC scenario, one of the key limitations in the design arises from an increased number of pile-up events O(1000), c.f. O(140) at HL-LHC, making both particle tracking and identification of vertices extremely challenging. This paper reviews the general ideas that conceptually drive the current tracker/vertex detector design for the FCC-hh (proton-proton). These include material budget, detector granularity, pattern recognition, primary vertexing/pile-up mitigation and occupancy/data rates. Finally, the limits of current tracker technologies and requirements on their future progress, i.e. the dedicated R&D;, are discussed
