25. Performance and calibration of boosted H(bb) tagging, including applications in physics analysis with ATLAS

The physics programme at ATLAS involves a variety of Standard Model and Beyond Standard Model resonances decaying to two b-quarks, or to a pair of bosons, including the Higgs Boson. In order to identify these resonances at high momentum, ATLAS has developed a boosted X?bb tagger, a new NN-based tagging algorithm which combines the flavour information of up to three sub-jets associated to the...

5. QCD physics measurements at the LHCb experiment

LHCb is a spectrometer that covers the forward region of proton-proton collisions, corresponding to the pseudo-rapidity range 2$<\eta<$5. In this unique phase space, LHCb can perform tests of perturbative and non-perturbative QCD models, by studying the production of heavy flavor quarks, like charm and top quarks. In this context the production of a Z boson in association with a c-jet can be...

17. Measurements of jet energy correlations and jet fragmentation, including heavy flavour, using the ATLAS detector

Javier Llorente Merino (Simon Fraser University (CA))

In this talk, we present measurements of jet energy-energy correlations and jet fragmentation properties using data collected by the ATLAS experiment at √s = 13 TeV. Measurements of transverse energy-energy correlations and their associated azimuthal asymmetries in multi-jet events are compared to next-to-leading-order perturbative QCD calculations and provide a precision test of QCD at large...
