Physics Prospects for a near-term Proton-Proton Collider Open
Hadron colliders at the energy frontier offer significant discovery potential through precise measurements of Standard Model processes and direct searches for new particles and interactions. A future hadron collider would enhance the explo…

Constraints on Future Analysis Metadata Systems in High Energy Physics Open
In high energy physics (HEP), analysis metadata comes in many forms—from theoretical cross-sections, to calibration corrections, to details about file processing. Correctly applying metadata is a crucial and often time-consuming step in an…

Fragmentation, underlying event and jet shapes at the Tevatron Open
Experimental tests of QCD processes, in particular fragmentation, underlying event and jet shape studies, are not only essential in their own right to allow an improved understanding of the theoretical models and their limitations but they…

Search for Heavy Top-like Quarks t-rime ---> Wq Using Lepton Plus Jets Events in 1.96-TeV p anti-p Collisions Open
We present the results of a search for a new heavy top-like quark, tprime, decaying to a W boson and another quark using the CDF II Detector in Run II of the Tevatron ppbar collider. New top-like quarks are predicted in a number of models …

Long Short-Term Memory (LSTM) networks with jet constituents for boosted top tagging at the LHC Open
Multivariate techniques based on engineered features have found wide adoption in the identification of jets resulting from hadronic top decays at the Large Hadron Collider (LHC). Recent Deep Learning developments in this area include the t…
