Abstract:<\/span><\/strong><\/p>\n

After the discovery of the Higgs boson in July 2012, the precise study of the electroweak symmetry breaking mechanism that is responsible for the mass in the Standard Model (SM) has been one of the principal physics targets at Large Hadron Collider (LHC) at CERN. Higgs boson property measurements of 1) Higgs boson mass and decay width, 2) Higgs boson couplings to gauge bosons and fermions and 3) Higgs boson quantum numbers JPC\u00a0<\/span>and tensor structure has been studied in detail. Besides, 4) the Higgs potential with Higgs self-coupling \u03bb is least known of today, and this remains as one of the key topics in future collider physics. The LHC accelerator has operated at the centre-of-mass energies at 7 and 8 TeV during 2010-2012, and has accumulated the integrated luminosity of about 25 fb\u2212<\/span>1\u00a0<\/span>in total. LHC in RUN-2 has started in spring 2015 and lasted until October 24th 2018 by accumulating an integrated luminosity of 150fb\u2212<\/span>1<\/span>\u00a0<\/span>at the entre-of-mass energy of 13 TeV. By the end of 2023 (RUN-3), it is expected to accumulate data up to 300fb\u2212<\/span>1<\/span>. The High-Luminosity-LHC (HL-LHC) is expected to start in 2026 aiming the integrated luminosity of 4 ab\u2212<\/span>1\u00a0<\/span>by 2038. In the absence of the direct hint for the physics beyond the Standard Model (BSM) at LHC, it is of primary importance to pursue precision Higgs physics to search for the deviation from the SM and search for the BSM Higgs signal at LHC RUN-2&3 and HL-LHC. The so-called \u03ba-framework used in RUN-1 by the LHC collaborations will no longer be adequate, because it cannot be improved beyond O(10%) precision and cannot capture all possible Higgs interactions that may arise in nature. Instead, the Higgs Effective Field Theory (EFT) is drawing a lot of attentions these days as general theoretical framework, which enables combining data with electroweak precision data, top-quark physics, etc. In the seminar, recent experimental results of Higgs property measurements and future prospects of precision Higgs physics with EFT will be discussed.<\/span><\/div>\n<\/div>\n","protected":false},"featured_media":0,"template":"","tags":[],"seminar_category":[54],"acf":{"s_now_accepting":false,"s_date_order":"2018-12-11 15:00:00","s_date_end":null,"s_date_text":"2018-12-11 3PM","s_text":"Reisaburo Tanaka (Laboratoire de l\u2019Acc\u00e9l\u00e9rateur Lin\u00e9aire, Univ.
