Overview on simulations for FCC   M.Klein  5.11.2020

FCC simulation for electroweak study using extended binning
which was used for LHeC in March 2017
-----------------------------------------------------------

Calculations are done of the uncertainties of the NC and CC
inclusive cross sections as can be expected for the FCC. 


The following sets are provided:


NC/CC Name             Ee[GeV]  Ep[TeV]  P(e)   Charge  Lum[ab-1]

nominal, high luminosity data, negative polarisation  
NC    datfcc5060ncem    60       50       -0.8    -1     2
CC    datfcc5060ccem    60       50       -0.8    -1     2

nominal, high luminosity data, opposite polarisation
NC    datfcc5060ncep    60       50        0.8    -1    0.5
CC    datfcc5060ccep    60       50        0.8    -1    0.5

positron data, unpolarised
NC    datfcc5060ncepp  60        50         0    +1     0.2
CC    datfcc5060ccepp  60        50         0    +1     0.2

low energy data, unpolarised (a poor LHeC replacement)
NC    datlhec160ncem   60        7         -0.8    -1   0.2
CC    datlhec160ccem   60        7         -0.8    -1   0.2

each  file has a header which should make the meaning of the numbers clear.

For the present simulation the following cuts were applied:

eta_max=5, .95 < y < 0.001

Error assumptions

energy scales: e: 0.1%,  h=0.5%  
      this is the D/MC scale difference

Radcor 0.3%  Photoproduction at high y: 1%
uncorrelated extra efficiency 0.5%

The luminosity error is kept aside, one may assume 0.5-1%.
