Rd btoxll add acceptance and loosen selection for electron lines

Requiring the following acceptance for electrons in the btoxll lines.

• Long tracks : InECAL , InBREM , ELECTRONID > 0 (hasCalo)
• Upstream tracks : InBREM
• Downstream tracks (Not included for these lines ) : InECAL , ELECTRONID > 0 (hasCalo)

To Do:

• Investigate loosening of B vtx chi2 and electron PIDe cuts
• Include HLT1 selection requirement?
• If HLT1 selection added (and potentially move to Turbo) could add DIRA(B) > 0.9999 to DIRA(B) > 0.9995, and PIDe > -2 to PIDe > -4

Efficiencies

Computed from fits to 24c4 data

Results from fits to 24c4 data:

• LL = '( ep_TRACKISLONG & em_TRACKISLONG )'
• UL = '( ep_TRACKISUPSTREAM | em_TRACKISUPSTREAM )'

BuToKpEE

• \epsilon( Acceptance | \text{ LL \& presel } ) = 86\%
• \epsilon( Acceptance | \text{ UL \& presel } ) = 88\%
• N( LL | \text{Pass Acceptance \& presel } ) = 277,262
• N( UL | \text{Pass Acceptance \& presel } ) = 55,502

B0ToKpKmEE

• \epsilon( Acceptance | \text{ LL \& presel }) = 83\%
• \epsilon( Acceptance | \text{ UL \& presel }) = 89\%
• N( LL | \text{Pass Acceptance \& presel } ) = 17,163
• N( UL | \text{Pass Acceptance \& presel } ) = 3,560

Cut Breakdown using B0ToKpKmEE 24c4 data fits

• \epsilon( InBrem | \text{ UL \& presel } ) = 88\%
• \epsilon( InEcal | \text{ LL \& presel } ) = 88\%
• \epsilon( InBrem | \text{ LL \& InEcal \& presel } ) = 97\%
• \epsilon( hasCalo | \text{ LL \& InEcal \& InBrem \& presel } ) = 99\%

Cut Breakdown using BuToKpEE 24c4 data

Here I have simply computed the % of all events in HTL2 output (24c4 data) surviving the selection (sample is background dominated)

Selection	Preselection	Survival %
InEcal	LL	13 %
InBrem	LL & InEcal	60 %
hasCalo	LL & InEcal & InBrem	96 %
InBrem	UL	16%

Selection	Preselection	Survival %
InEcal	LL & HLT1	46 %
InBrem	LL & InEcal & HLT1	85 %
hasCalo	LL & InEcal & InBrem & HLT1	98 %
InBrem	UL & HLT1	47%

Where HLT1 is defined as:

'\
( Bp_Hlt1TrackMVADecision_TOS | Bp_Hlt1TwoTrackMVADecision_TOS ) \
| \
Bp_Hlt1TrackElectronMVADecision_TOS \
| \
Bp_Hlt1SingleHighPtElectronDecision_TOS \
| \
Bp_Hlt1DiElectronDisplacedDecision_TOS \
| \
Bp_Hlt1DiElectronHighMass_SSDecision_TOS \
| \
Bp_Hlt1DiElectronHighMassDecision_TOS \
| \
Bp_Hlt1DiElectronLowMass_massSlice1_displacedDecision_TOS \
| \
Bp_Hlt1DiElectronLowMass_massSlice2_displacedDecision_TOS \
| \
Bp_Hlt1DiElectronLowMass_massSlice3_displacedDecision_TOS \
| \

For fits to data with the preselection:

'6.0 < q2_ConsB < 11.0 & Kp_PID_K > 4 & ( Bp_Hlt1TrackMVADecision_TOS | Bp_Hlt1TwoTrackMVADecision_TOS )'
'6.0 < q2_ConsB < 11.0 & ( 1_010 < phi_M < 1_030 ) & Kp_PID_K > 4 & Km_PID_K > 4 & ( Bs0_Hlt1TrackMVADecision_TOS | Bs0_Hlt1TwoTrackMVADecision_TOS )'
