[QEE] Exp.2023 conditions for electroweak early-measurement

For electroweak analyses on the 2023 data, want appropriate up-to-date simulation that matches the detector conditions.

Beam6800GeV-expected-2023-VeloClosed23.5mm-MagDown-Nu1.4-25ns-Pythia8

N_events chosen by discussion: !179 (comment 7019478) Requesting samples for the following event types:

• Z/Gamma*->mu mu (1 lepton with pT>4GeV, invariant mass cut 40GeV): 42112001 : 100k
• Jpsi(1S)->mu mu (radiative mode included, daughters in acceptance): 24142001 : 4M
• Upsilon(1S)->mu mu (radiative mode included, daughters in acceptance): 18112001 : 2M
• W->mu nu_mu (lepton_pt > 10GeV cut): 42311003 : 2M
• W->tau nu_tau->mu (mu_pt > 10GeV cut): 42300001 : 300k

Calculated via 10*Lumi * Cross-section, for the ~50pb^-1 of data we have available.

ToDo:

• Add a W->tau nu background.
• Estimate the needed number of events from the xsec, lumi, trigger efficiencies etc.
