Identification of Lorentz-boosted jets in the CMS experiment / Troiano, Donato (INFN, Bari ; Bari U.) /CMS Collaboration
A focus of the CMS research involves identifying jets originated from quarks and gluons produced in high-energy proton-proton collisions. At the electroweak scale, resonances like the Z and W bosons, as well as the Higgs boson, are often produced with a significant Lorentz boost, causing their decay products to form large and massive jets, typically reconstructed as AK8 jets. [...]

Boosted jet identification at the CMS experiment / Troiano, Donato (INFN, Bari ; Bari U.) /CMS Collaboration
A fundamental aspect of the CMS experiment's research concerns the identification of jets produced in high energy proton-proton collisions. W and Z bosons and the Higgs boson can be produced with a high Lorentz boost and, under such conditions, their decay products can be reconstructed as large radius jets, \textit{i.e.}, anti-$k_{t}$ jets of radius 0.8 (AK8).

Identification of highly Lorentz-boosted heavy particles using graph neural networks and new mass decorrelation techniques /CMS Collaboration
This note presents several new developments on machine learning (ML)-based identification of highly Lorentz-boosted heavy particles using jet substructure in CMS and their performance with the CMS Phase 1 detector. A new algorithm based on ParticleNet, a graph neural network using an unordered set of jet constituent particles as the input, has been developed and shows significantly improved performance. [...]
