[QEE] Exp.2024 conditions for electroweak early-measurement.

Postponed until Mar-27th

From this presentation by gloria https://indico.cern.ch/event/1369228/#7-simulation-for-2024-data (Thanks Emir for sharing this!)

26-Mar: Freeze geometry, conditions Gauss and Boole for 2024 with best knowledge.

As we want this for Data/MC comparisons and early performance studies etc. it's probably best to wait for this Freeze.

Now Live! See: !479 (comment 7782826)

Request

For electroweak analyses on the 2024 data, want appropriate up-to-date simulation that matches the detector conditions.

event-code	#Events/Pol [k]	Short Descr.
42112001	500	Z/Gamma*->mu mu (1 lepton with pT>4GeV, invariant mass cut 40GeV)
42100001	500	Z/Gamma*->tau tau (1 lepton with pT > 4 GeV,invariant mass>40GeV)
42311003	2,500	W->mu nu_mu (lepton_pt > 10GeV)
42300001	1,500	W->tau nu_tau ->mu (mu_pt > 10GeV)
42112015	250	Dimuon DrellYan (muon PT>1GeV, dimuon invarmass > 20GeV && < 40GeV)
49000011	25,000	QcdBgd (1 particle in the acceptance with pT > 18 GeV with Hard QCD enabled)
49011014	1,500	ccbar->mu X (muon pt > 14 GeV, within acceptance. Phase space cuts.)
49011015	6,500	bbbar->mu X (muon pt > 14 GeV, within acceptance. Phase space cuts.)
24142001	4,000	Jpsi(1S)->mu mu (radiative mode included, daughters in acceptance)
18112001	4,000	Upsilon(1S) -> mu mu (radiative mode included, daughters in acceptance)
42122001	500	Z/Gamma*->e e (1 lepton with pT>4GeV, invariant mass cut 40GeV)

Evts Calculated via:
mc:data * Lumi * Cross-section. (Rounded to be nice numbers 🙂)
mc:data ~ 1.5. [Chosen to get just below PPG limit of 100M total events per request]
lumi = 1/fb.

• For reference: ~7fb^-1 is the target for 2024.
  All eventcodes starting with 4 have Cross-sections taken from https://gitlab.cern.ch/LHCb-QEE/ew-analyses/-/blob/master/data/cross_sections/decfile/13600.json
  Jpsi and Upsilon more hand-wavily calculated with respect to Z cross-section.

NB: QcdBgd = 49000011 with 18B events cut down to 50M/polarity to be more reasonable/responsible.

ToDo:

• Discuss with other EW proponents.
  • Add Z/g->ee mode : 42122001
• Approval from Liaison
