Abstract

We consider a supersymmetric (SUSY) scenario including right-handed neutrinos, one of whose scalar superpartners is the lightest SUSY particle. The distinguishing feature in the collider signal of SUSY in such a case is not missing energy but a pair of charged tracks corresponding to the next-to-lightest SUSY particle, when it is, as in the case considered, a stau. Following up on our recent work on neutralino reconstruction in such cases, we explore the possibility of reconstructing charginos, too, through a study of transverse mass distributions in specified final states. The various steps of isolating the transverse momenta of neutrinos relevant for this are outlined, and regions of the parameter space where our procedure works are identified.

Neutralino reconstruction in supersymmetry with long-lived staus

Journal Article Biswas, Sanjoy; Mukhopadhyaya, Biswarup - Physical Review. D, Particles Fields

We consider a supergravity scenario, with universal scalar and gaugino masses at high scale, with a right-chiral neutrino superfield included in the spectrum. Such a scenario can have the lightest supersymmetric particle (LSP) dominated by the right sneutrino and a stau as the next-to lightest supersymmetric particle (NLSP). Since decays of all particles into the LSP are suppressed by the neutrino Yukawa coupling, the signal of supersymmetry consists of charged tracks of stable particles in the muon chamber. We demonstrate how a neutralino decaying into a tau and the stau NLSP can be fully reconstructed over substantial areas in themore »« less

Reconstruction of the left-chiral tau sneutrino in supersymmetry with a right sneutrino as the lightest supersymmetric particle

Journal Article Biswas, Sanjoy - Physical Review. D, Particles Fields

We have considered a supersymmetric scenario in which the minimal supersymmetric standard model is augmented with a right-chiral neutrino superfield for each generation. Such a scenario can have a lightest supersymmetric particle (LSP) dominated by the right-chiral sneutrino state and the lighter stau as the next-to-lightest supersymmetric particle (NLSP). This can easily be motivated by assuming a high-scale framework of supersymmetry breaking like minimal supergravity (mSUGRA). Because of the extremely small neutrino Yukawa coupling, the decay of the NLSP to the LSP is suppressed and, consequently, the NLSP - here the lighter stau mass eigenstate -becomes stable at the lengthmore »« less

Search for Associated Chargino-Neutralino Production in Proton-Antiproton Collisions at 1.96 TeV

Thesis/Dissertation Blumenschein, Ulla

The search for a fundamental theory of matter and forces in the universe has ever since attracted the interest of physicists. The large success of the gauge theories in the description of low-energy phenomena nourishes the hope that gauge symmetries are the clue to a unified description of all fundamental processes at high energy scales. Particle collision experiments of the past decades have probed the structure of matter with increasing resolution. The phenomena observed in collision experiments at current energy scales are described with a large precision by the Standard Model of particle physics. Nevertheless, many open questions in themore »« less

Constraining the compressed spectrum of the top squark and chargino along the $W$ corridor

Journal Article Cheng, Hsin-Chia; Li, Lingfeng; Qin, Qin - Physical Review. D.

Studying superpartner production together with a hard initial state radiation jet has been a useful strategy for searches of supersymmetry with a compressed spectrum at the LHC. In the case of the top squark (stop), the ratio of the missing transverse momentum from the lightest neutralinos and the initial state radiation momentum, defined as R _M, turns out to be an effective variable to distinguish the signal from the backgrounds. It has helped to exclude the stop mass below 590 GeV along the top corridor where m$$\sim\atop{t}$$ -m$$\sim\atop{\chi}$$ $$0\atop{1}$$ ≈ m_t. On the other hand, the current experimental limit ismore »« less

Search for chargino-neutralino production using recursive jigsaw reconstruction in final states with two or three charged leptons in proton-proton collisions at $\sqrt{s} = 13 TeV$ with the ATLAS detector

Journal Article Aaboud, M.; Aad, G.; Abbott, B.; ... - Physical Review. D.

A search for electroweak production of supersymmetric particles is performed in two-lepton and threelepton final states using recursive jigsaw reconstruction, a technique that assigns reconstructed objects to the most probable hemispheres of the decay trees, allowing one to construct tailored kinematic variables to separate the signal and background. The search uses data collected in 2015 and 2016 by the ATLAS experiment in $$ \sqrt{s}$$ = 13 TeV proton-proton collisions at the CERN Large Hadron Collider corresponding to an integrated luminosity of 36.1 fb^-1. Chargino-neutralino pair production, with decays via W/Z bosons, is studied in final states involving leptons and jetsmore »« less
