Search for top squark pair production in a final state with at least one hadronically decaying tau lepton in proton-proton collisions at √s=13 TeV

Matthias Finger, Konstantin Androsov, Qian Wang, Jan Steggemann, Yiming Li, Anna Mascellani, Varun Sharma, Xin Chen, Rakesh Chawla, Matteo Galli

A search for pair production of the supersymmetric partner of the top quark, the top squark, in proton-proton collisions at root s = 13TeV is presented in final states containing at least one hadronically decaying tau lepton and large missing transverse mo ...

Reconstruction of decays to merged photons using end-to-end deep learning with domain continuation in the CMS detector

Matthias Finger, Konstantin Androsov, Qian Wang, Jan Steggemann, Yiming Li, Varun Sharma, Xin Chen, Arvind Shah, Rakesh Chawla, Jian Wang

A novel technique based on machine learning is introduced to reconstruct the decays of highly Lorentz boosted particles. Using an end-to-end deep learning strategy, the technique bypasses existing rule-based particle reconstruction methods typically used i ...

Search for top squark production in fully hadronic final states in proton-proton collisions at root s=13 TeV

Konstantin Androsov, Matthias Finger, Jan Steggemann, Qian Wang, Yiming Li, Varun Sharma, Xin Chen, Arvind Shah, Rakesh Chawla, Jian Wang

A search for production of the supersymmetric partners of the top quark, top squarks, is presented. The search is based on proton-proton collision events containing multiple jets, no leptons, and large transverse momentum imbalance. The data were collected ...

Sensitivity of the SHiP experiment to Heavy Neutral Leptons

Lesya Shchutska, Aurelio Bay, Elena Graverini, Guido Haefeli, Florian Maria Wurm, Mikhail Chapochnikov, Alexey Boyarsky, Sun Hee Kim, Federico Leo Redi, Oleg Ruchayskiy

Heavy Neutral Leptons (HNLs) are hypothetical particles predicted by many extensions of the Standard Model. These particles can, among other things, explain the origin of neutrino masses, generate the observed matter-antimatter asymmetry in the Universe an ...
