Activities (‘ 17. 05~’ 17. 10) CERN-CKC Workshop + CERN TH Institute ▶ The 2017 CERN-CKC Workshop: What’s Going on at the Weak Scale? (’ 17. 05. 31~’ 17. 06) - 79 participants including 39 Korean participants - 6 Korean speakers (Doojin Kim, Minho Son, Sunghoon Jung, Jong-Chul Park, Hyungjin Kim, Chang Sub Shin) ▶ TH Institute: “Geometry of String and Gauge Theories” (’ 17. 07. 10~’ 17. 07. 21) - 40 participants including 14 Korean participants - 6 Korean speakers (Sangmin Lee, Jaewon Song, Jiwon Choi, Seung Joo Lee, Heeyeon Kim, Jin-Beom Bae)

Plan (‘ 17. 10~’ 18. 09: 10 months) ▶ Select 1 CERN fellow - Regular fellow for 2 years (to start from ’ 18. 09) - Selection to be completed by ‘ 18. 01 ▶ Select 1 graduate students - 6 months (to start before ‘ 18. 03) ▶ Have 2 CERN-CKC TH Institutes - BSM (‘ 18. 08. 12. ~’ 18. 08. 25. , CERN) - 1 TH Institute on Field and String Theory (under plan, Summer 2018, CERN)

Future Plan ▶ Continue monitoring CERN-CKC fellow and grad-student programs with the aim of ensuring their impact on Korean science in the future, and optimizing this impact if possible. ▶ Organize 1 CERN-CKC TH Institute in Korea every 3 years ▶ Promote active collaborations with Korean experimental groups (KCMS and Ko. ALICE) and active participations of other Korean particle theorists in TH institutes

Conclusion ▶ The CERN-Korea theory collaboration program have provided/ will provide Korean young researchers with great opportunities for accelerating their careers. ▶ The CERN-Korea TH institute program is going well in 2017 It should keep being fully supported with increasing fund. ▶ We keep promoting close collaborations between Korean participating members (and other Korean particle physics theorists) with CERN staffs for world-class HEP researches.
