11.2. Physics skims#

11.2.1. B → charm skims#

List of functions to skim events containing \(B\to X_c + h\) decays, where \(X_c\) stands for \(D^0\), \(D^{\pm}\), \(D^{*0}\) and \(D^{*\pm}\), and \(h\) stands for \(\pi^{\pm}\), \(K^{\pm}\), \(\rho^{\pm}\) and \(a_1^{\pm}\).

This skim includes a selection on the HLT flag hlt_hadron.

Reconstructed decay modes:

\(B^{0}\to \overline{D}{}^{0} (\to K^+ \pi^- \pi^0) \pi^0\)

Cuts applied:

Mbc > 5.2
abs(deltaE) < 0.5

Note

This skim uses skim.standardlists.charm.loadStdD0_Kpipi0, where the \(\overline{D}{}^{0}\) channel is defined.

ApplyHLTHadronCut = True#: If this property is set to True, then the HLT selection for hlt_hadron will be applied to the skim lists when the skim is added to the path.

load_standard_lists(path)[source]#

produce_on_tau_samples = False#

If this property is set to False, then b2skim-prod will not produce data production requests for this skim on taupair MC samples. This decision may be made for one of two reasons:

The retention rate of the skim on taupair samples is basically zero, so there is no point producing the skim for these samples.
The retention rate of the skim on taupair samples is too high (>20%), so the production system may struggle to handle the jobs.

produce_on_tau_samples = False#

If this property is set to False, then b2skim-prod will not produce data production requests for this skim on taupair MC samples. This decision may be made for one of two reasons:

The retention rate of the skim on taupair samples is basically zero, so there is no point producing the skim for these samples.
The retention rate of the skim on taupair samples is too high (>20%), so the production system may struggle to handle the jobs.

11.2.3. Charm physics skims#

Skim list building functions for charm analyses.

Note

The Hp, Hm and Jm in the function name represent arbitrary charged particles with positive or negative charge. The Hp and Jm in XToD0_D0ToHpJm, mean a positive particle and a negative particle that could be either conjugate or non-conjugate. The Hp and Hm in EarlyData_DstToD0Pi_D0ToHpHmPi0, mean a positive particle and a negative particle that must be conjugate.

Note

Although reconstructDecay() would automatically include charged conjugate channel, and D0 is not distinguishable from anti-D0 in XToD0 skim, both \(D^0 \to f\) and \(D^0 \to \overline{f}\) mode should be written explicitly in XToD0 skim, because later in the DstToD0Pi skim, the D0 decay strings in XToD0 skim would be directly combined with pi+. For example, if one only include D0 -> K+ pi- in XToD0_D0ToHpJm skim, then in DstToD0Pi_D0ToHpJm skim, only the D*+ -> [D0 -> K+ pi-] pi+ would be included, and D*+ -> [D0 -> K- pi+] pi+ would not be included.

(Maybe in the future, we can add a loose ECL cluster timing cut to \(\pi^{0}\) in this skim.)

Parameters:

path (basf2.Path): Skim path to be processed.

Returns:

List of D0 particle list names.

NoisyModules = ['ParticleLoader', 'RootOutput']#: List of module types to be silenced. This may be necessary in certain skims in order to keep log file sizes small.

Tip

The elements of this list should be the module type, which is not necessarily the same as the module name. The module type can be inspected in Python via module.type().

ApplyHLTHadronCut = True#: If this property is set to True, then the HLT selection for hlt_hadron will be applied to the skim lists when the skim is added to the path.

FEIChannelArgs = {}#: Dict of str -> bool pairs to be passed to fei.get_default_channels. When inheriting from BaseFEISkim, override this value to apply the FEI for only e.g. SL charged \(B\)’s.

FEIPrefix = 'FEIv4_2022_MC15_light-2205-abys'#: Prefix label for the FEI training used in the FEI skims.

MergeDataStructures = {'FEIChannelArgs': <function _merge_boolean_dicts>}#: Dict of str -> function pairs to determine if any special data structures should be merged when combining skims. Currently, this is only used to merge FEI config parameters when running multiple FEI skims at once, so that it can be run just once with all the necessary arguments.

NoisyModules = ['ParticleCombiner']#: List of module types to be silenced. This may be necessary in certain skims in order to keep log file sizes small.

Tip

The elements of this list should be the module type, which is not necessarily the same as the module name. The module type can be inspected in Python via module.type().

This attribute is used by BaseSkim.set_skim_logging.

additional_setup(path)[source]#

Apply pre-FEI event-level cuts and apply the FEI. This setup function is run by all FEI skims, so they all have the same event-level pre-cuts.

This function passes FEIChannelArgs to the cached function run_fei_for_skims to avoid applying the FEI twice.

See also

fei_precuts for event-level cut definitions.

static fei_precuts(path)[source]#

Skim pre-cuts are applied before running the FEI, to reduce computation time. This setup function is run by all FEI skims, so they all have the save event-level pre-cuts:

\(n_{\text{cleaned tracks}} \geq 3\)
\(n_{\text{cleaned ECL clusters}} \geq 3\)
\(\text{Visible energy of event (CMS frame)}>4~{\rm GeV}\)

We define “cleaned” tracks and clusters as:

Cleaned tracks (pi+:FEI_cleaned): \(d_0 < 0.5~{\rm cm}\), \(|z_0| < 2~{\rm cm}\), and \(p_T > 0.1~{\rm GeV}\)
Cleaned ECL clusters (gamma:FEI_cleaned): \(\theta\) in CDC acceptance, and \(E>0.1~{\rm GeV}\)

produce_on_tau_samples = False#

If this property is set to False, then b2skim-prod will not produce data production requests for this skim on taupair MC samples. This decision may be made for one of two reasons:

The retention rate of the skim on taupair samples is basically zero, so there is no point producing the skim for these samples.
The retention rate of the skim on taupair samples is too high (>20%), so the production system may struggle to handle the jobs.

static run_fei_for_skims(FEIChannelArgs, FEIPrefix, analysisGlobaltag, *, path)[source]#

Reconstruct hadronic and semileptonic \(B^0\) and \(B^+\) tags using the generically trained FEI.

Parameters:

FEIChannelArgs (dict(str, bool)) – A dict of keyword-boolean pairs to be passed to fei.get_default_channels.
FEIPrefix (str) – Prefix label for the FEI training used in the FEI skims.
path (basf2.Path) – The skim path to be processed.

produce_on_tau_samples = False#

If this property is set to False, then b2skim-prod will not produce data production requests for this skim on taupair MC samples. This decision may be made for one of two reasons:

The retention rate of the skim on taupair samples is basically zero, so there is no point producing the skim for these samples.
The retention rate of the skim on taupair samples is too high (>20%), so the production system may struggle to handle the jobs.

produce_on_tau_samples = False#

If this property is set to False, then b2skim-prod will not produce data production requests for this skim on taupair MC samples. This decision may be made for one of two reasons:

The retention rate of the skim on taupair samples is basically zero, so there is no point producing the skim for these samples.
The retention rate of the skim on taupair samples is too high (>20%), so the production system may struggle to handle the jobs.
