14:25 → 14:30 Jet Physics and Beyond!

I will briefly introduce myself, jet physics and my current research on inclusive jet and dijet cross-section data of ATLAS and CMS. In the end of this talk, I want to share my perspectives as a summer student at CERN in this exciting moment for particle physics.

Slides Determination_of_the_Muon_Reconstruction_Efficiency_using_the_Z-μμ_events_in_p-p_Collisions.pdf Determination_of_the_Muon_Reconstruction_Efficiency_using_the_Z-μμ_events_in_p-p_Collisions.pptx

14:35 → 14:40 Resolving the Neutrino Ambiguity

Continuation of the first talk on how to maximize the reconstruction of the single top produced through electroweak processes, with the focus on the leptonic channel due to the high probability of new physics appearing in such channels. In this short talk, the simple rudimentary tactics that were applied to a Monte Carlo single top sample and their effectiveness will be discussed.

Speaker: Mr Kelvin Mei (Rutgers, State Univ. of New Jersey (US))

14:50 → 14:55 Top Reconstruction Techniques in 0-Lepton Direct Stop Searches

I will discuss my current research into new and improved methods for identifying top quarks in 6+ jet events with missing transverse energy. Specifically, I will discuss methods I have developed to reconstruct tops, and my future plans for my project in the coming weeks.

Speaker: Anthony James Kremin (University of Michigan (US))

Slides REU_SecondPresentation.pdf REU_SecondPresentation.pptx

15:00 → 15:05 Feasibility study of the measurement of absolute branching fractions of the Λc baryon

Decays of the heavy baryons Λc+ and Λb are presently affected by a large uncertainty of 22% in the decay of Λc. As a result, it is meaningful to find a way to tag it by MC.

Speaker: Yi Bao (CERN)

15:10 → 15:15 Vector Boson Fusion At High Mass

A SM Higgs boson or other new physics can affect the process of vector boson scattering and the cross section behavior is quite different at high energy. New heavy resonances may be found.( I hope so)

Speaker: Hanzhe Liu (Univ. of Science & Tech. of China (CN))
