"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."

6th KEK-PH + 2nd KEK-COSMO joint mini-workshop

This time the KEK Theory Center is organizing the phenomenology and cosmology-themed mini workshop, the 6th KEK-PH and the 2nd KEK-Cosmo, which is mainly made up of contribution talks by young researchers held on 9th and 10th, March, 2022.  Prior to the session of the contributed talks, on the morning of the 9th, we are going to hold a special invited talk by Prof. Wei Xue (U of Florida) about the structure formation by axion.
Plenary session

Prof. Wei Xue (University of Florida), "Resonant excitation of the axion field during the QCD phase transition"

Short talk sessions

 Mar. 9th (Wed.) 13:30-16:55 and Mar. 10th (Thu.) 11:00-16:55

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"
