Physics of the Higgs boson

Related to the so far only discovery at LHC, Higgs studies are in the focus of future HEP projects. At ILC and Belgrade HEP group is in charge of several Higgs coupling measurements, namely in Higgs decays to EW bosons (WW and ZZ) in hadronic and semileptonic final states, at 500 GeV ILC and 350 GeV, 1.4 TeV and 3 TeV CLIC, then for rare Higgs decays – to muons at 1.4 TeV CLIC and 2 photons at 3 TeV CLIC. Results have been or about to be published in Eur.Phys.Journal C, and presented at LCWS meetings, ICHEP and other conferences. There are 2 ongoing PhD theses related to the Higgs studies.

H→WW* decay at a 500 GeV ILC

Analysis of the fully hadronic (WW→qqqq) final state. Read more.

H→WW* decay at the 350 GeV CLIC

Analysis of the fully hadronic (WW→qqqq, Z→qq) and the semileptonic (WW*→qqqq, Z→ll) final states. Read more.

H→µ+µ- decay at the 1.4 TeV CLIC

Two-muon Higgs decay measurement is studied at a 1.4 TeV CLIC. Eur. Phys. J. C75 (2015) 515 is the first paper addressing this measurement.

H→ZZ* decay at a 1.4 TeV CLIC

Fully hadronic (ZZ*→qqqq) and the semileptonic (ZZ*→qql+l-) final states of the H&rarrow;ZZ* decays at 1.4 TeV. Read more here.

H→WW* decay at the 3 TeV CLIC

Analysis of the fully hadronic (WW*→qqqq) final state of the H→WW* decay at a 3 TeV CLIC. Read more.

H→γγ decay at a 3 TeV CLIC
