Top/EW/QCD: 1
- Freya Blekman (Deutsches Elektronen-Synchrotron (DE))
This measurement is performed using highly boosted top quark pair events resulting in non isolated leptons and overlapping jets. Jet substructure variables are used to identify the boosted top quark and the W boson. The top quark charge asymmetry is measured for events with ttbar invariant mass larger than 750 GeV and corrected for detector and acceptance effects using a binned maximum...
Microscopic BSM dynamics can be encoded in a small set of parameters controlling deformations from the SM. I argue that sensitivity to BSM physics can be boosted with observables that discriminate longitudinal and transverse production of EW vectors. This is well studied in leptonic decays, but recently, with the help of energy correlators, studies started to target hadronic decays.
I show...
Final states in collider experiments are characterized by correlation functions of the energy flow operator - which plays the roll of an idealised calorimeter. In this talk, I will show that the boosted top quark imprints itself as a peak in the three-point correlator at an angle determined by its mass and transverse momentum. This provides direct access to one of the most important parameters...
We present a measurement of the jet mass distribution in fully hadronic decays of boosted top quarks with full Run 2 data. The measurement is performed in the lepton+jets channel of top quark pair production. The top quark decay products of the all-hadronic decay cascade are reconstructed with a single large-radius jet with transverse momentum greater than 400 GeV. The top quark mass is...
In this talk, we study prospects for measuring the strong coupling $\alpha_s$ using the soft-drop jet-mass cross section in hadronic collisions. We compute the normalized cross section for quark and gluon jets to NNLL accuracy, and estimate the nonperturbative hadronization corrections using a model-independent field-theory based formalism involving $\mathcal{O}(\Lambda_{\rm QCD})$ constants...
