"KEK-PH lectures and workshops" is a form of KEK-PH workshop series at the time of Covid-19.

The annual KEK Theory Meeting on Particle Physics Phenomenology (KEK-PH) covers many topics in Particle Physics and Cosmology, from the Standard Model and models beyond it to particle cosmology and astrophysics. At the time of Covid-19, the KEK theory center is organizing an on-line lecture and workshop series, "KEK-PH lectures and workshops 2021."

The 5th KEK-PH on "Jet Physics"

In the search for new physics at the LHC experiment, jet is often produced from heavy particle decays. By studying the jet structure, we can reconstruct particles with high momentum, such as W, Z, top, and H, and increase the sensitivity to new physics. In "KEK-PH Jet Physics", we will discuss recent theoretical developments, the latest data from the ATLAS and CMS experiments, and the expected sensitivity at the HL-LHC from both theoretical and experimental perspectives.
Invited talks
Nov. 30th (Tue.)
16:15-17:00:  Prof. Takuya Nobe (ICEPP, Tokyo), "Jet physics with ATLAS"
17:00-18:00:  Prof. Gavin Salam (Oxford), "Jets through the LHC era"
Dec. 1st (Wed.)
10:00-10:45: Prof. Cristina Mantilla (FermiLab), "Boosted jet physics in CMS" 


The 4th KEK-PH on "New Ideas in Particle Physics"

We are now preparing a workshop on "New ideas in particle physics," on Nov. 16 and 17. This time, it is a joint workshop with Florida State University (co-organizer: Kosaku Tobioka). The topics cover cosmological solutions to the naturalness problems, swampland conjectures, as well as quantum gravity effects on low energy physics.
