New clustering algorithm for multijet cross sections in e+e− annihilation

“…For the C-parameter an alternative coefficient for the α s Λ/Q power correction has been proposed in [124], however since it also is not based on a full calculation of the power correction in the three-jet region (which does not yet exist), it is subject to precisely the same reservations as eq. (25).…”

The investigation of the Higgs boson, especially the verification of the mass generation mechanism, is one of the most important themes for particle physics after the discovery of the Higgs boson. To achieve this, the International Linear Collider (ILC) is proposed as a next generation electronpositron collider. We evaluate the measurement accuracy of the Higgs branching ratio into tau pairs at the ILC with a full simulation of the ILD detector concept. We assume a center-of-mass energy of √ s = 250 GeV, beam polarizations of P(e − , e + ) = (−0.8, +0.3), and an integrated luminosity of 250 fb −1 . We obtain the measurement accuracy ∆(σ · Br)/(σ · Br) = 3.5 % for a Higgs boson mass of M h = 120 GeV. The result scaled to M h = 125 GeV is estimated to be 4.2 %.

Production of exclusive dijets in diffractive deep inelastic e ± p scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 372 pb -1 . The measurement was performed for γ * -p centre-of-mass energies in the range 90 < W < 250 GeV and for photon virtualities Q 2 > 25 GeV 2 . Energy and transverse-energy flows around the jet axis are presented. The cross section is presented as a function of β and φ , where β = x/x IP , x is the Bjorken variable and x IP is the proton fractional longitudinal momentum loss. The angle φ is defined by the γ * -dijet plane and the γ * -e ± plane in the rest frame of the diffractive final state. The φ cross section is measured in bins of β . The results are compared to predictions from models based on different assumptions about the nature of the diffractive exchange.
