Untagged, Prompt tagged, SL single and double tagged lines, as well as some low bias untagged and prompt tagged lines for Charm D02Kshh lines using Thor functors.

The untagged lines can be used in analysis such as yCP in D0->KsKK decays which don't require any flavour tagging. Therefore these untagged lines will help boost the statistics in such analysis which at present are statistically limited.

Untagged

D0 -> pi+ pi- (KS -> pi+ pi-), with low bias
D0 -> K+ K- (KS -> pi+ pi-), with low bias
D0 -> pi+ K- (KS -> pi+ pi-) and its charge conjugate, with low bias

Prompt tagged

D*(2010)+ -> (D0 -> pi+ pi- (KS -> pi+ pi-))pi+, with low bias
D*(2010)+ -> (D0 -> K+ K- (KS -> pi+ pi-))pi+, with low bias
D*(2010)+ -> (D0 -> pi+ K- (KS -> pi+ pi-))pi+ and its charge conjugate, with low bias

SL single tagged

B -> (D0 -> pi+ pi- (KS -> pi+ pi-))pi+) mu- X
B -> (D0 -> K+ K- (KS -> pi+ pi-))pi+) mu- X
B -> (D0 -> pi+ K- (KS -> pi+ pi-))pi+) mu- X and its charge conjugate

SL double tagged

B -> (D*(2010)+ -> (D0 -> pi+ pi- (KS -> pi+ pi-))pi+) mu- X
B -> (D*(2010)+ -> (D0 -> K+ K- (KS -> pi+ pi-))pi+) mu- X
B -> (D*(2010)+ -> (D0 -> pi+ K- (KS -> pi+ pi-))pi+) mu- X and its charge conjugate

There are separate lines for each of the above for when the KS is reconstructed with long pions and with down pions.

(Rates in kHz are obtained by by multiplying the efficiency in % by 10)

Current exclusive rates (see !1316 (merged) )

< moore    #=14983   Sum=1056  Eff=|( 7.047988 +- 0.209104)%|
> moore    #=14983   Sum=1088  Eff=|( 7.261563 +- 0.212005)%|

I.e. this MR adds around 2.1 kHz.
