Analysis goal

Measurement of the triple gauge couplings in the WW final state CLIC is a gauge boson factory important for EFT1 analyses JHEP 05, 096 (2017)

scale of new physics is large and EFT serves as low energy description

chose qqlν final state:

Datasets

Sample ID Xsec [fb] Signal qqln 3249 4309.7 Bkg qqln 3249 4309.7 Bkg qqll 3246 2725.8 Bkg qqqqln 5594 110.4 Bkg qqqqll 5572 62.1 Bkg qqqq 4034 1245.1 Bkg qqnn 2094 933.9 Bkg qqqqnn 5527 23.2

Table: Samples used in the analysis

The events in the datasets are scaled with the luminosity (1.5 ab−1) and their cross-section. Additionally, they are divided by the total number of entries in the dataset. W and WW → qqlν are separated by MC truth leptonic and hadronic W± boson masses both be < 100 GeV.

Physics objects

The physics objects used in this analysis are: Leptons

Isolated leptons

Jets

use Pandora PFOs without isolated leptons reconstructed using the Valencia alrogithm2 with

jet size R = 0.8 clustering order β = 1.0 jet shrinking for forward jets γ = 0.7

Missing energy

Initial state minus sum of selected jets and lepton

Event selection

A preliminary list of event selection cuts has been applied to select the qqlν final state: Pre-cut - an intermediate step to see separate effects

Exactly one charged lepton Exactly one muon (electrons are still undressed and left out for now)

Final - the preliminary full event selection

The pre-cut selection Remove events with forward jets by requiring | cos θ| < 0.95 Maximum total jet energy < 750 GeV Lepton pT > 30 GeV

Lepton dressing

Electrons (and to a lesser extent) muons radiate photons as they traverse the

• detector. These photons are reconstructed as separate particles, while actually

belonging to their mother electron. Clustering the photons in the vicinity of a lepton candidate helps recovering this energy which would otherwhise be lost. This improves the overall quality of the lepton reconstruction. The IsolatedLeptonFinder is being extended with an option to produce dressed

• leptons. It can be set to either replace the regular lepton container or be

produced in addition, for comparison and tuning. Status: the main functionality is implemented lively discussion on GitHub.

Conclusion

The analysis of the e+e− → qqlν channel is ongoing. The next steps are: rerun the analysis with updated missing energy (running as we speak) refine the event selection (e.g. select high √

s′ events)

determine differential cross-sections estimate efficiencies The lepton dressing is being implemented in ILCsoft. The next steps are: minimize the programmatical overhead of the new functionality add sensible steering parameters and defaults Thank you for your attention, feedback is very welcome!
