$$W^+_{} W^-_{} H$$ W + W - H production at lepton colliders: a new hope for heavy neutral leptons

W+/-H+/- production at hadron colliders.

Associated W±H∓ production at e+e− and hadron colliders

We show some results in the minimal supersymmetric Standard Model (MSSM) and the two Higgs doublet model (THDM) for WH production cross sections at ee and hadron colliders. 1 We demonstrate that the predictions for the cross sections in the two models can be vastly different. Observing these processes, once the existence of a charged Higgs is established, might shed some light on the underlying...

Measuring the top-quark Yukawa coupling at hadron colliders via tt̄h, h → W+W−

We study the signal and background for the process tt̄h, h → WW at the LHC and a 100 TeV VLHC. Signals are studied in two-, three-, and four-lepton final states. We find a statistical uncertainty in the top-quark Yukawa coupling at the LHC of 16%, 8%, 12% for mh = 130, 160, 190 GeV, respectively. The statistical uncertainty at the VLHC is likely to be negligible in comparison with the systematic...

Exploiting h!W W Decays at the Upgraded Fermilab Tevatron

We study the observability of a Standard Model-like Higgs boson at an upgraded Fermilab Tevatron via the mode h ! W W . We perform detector level simulations for the gg ! h ! W W ! ` ̀ and q q ! W h ! W W W ! ` ` jj channels. We nd that with a c. m. energy of 2 TeV and an integrated luminosity of 30 fb 1 the signal should be observable at a 3 level or better for the mass range of 145 GeV < mh < ...

Dr W. H. Hylton

Dr William H. Hylton, formerly a general practitioner in Clevedon died suddenly on March 20th at the age of 83. William Hawkins Hylton?Bill, was born in Leeds in 1906. He was educated at Bridlington College. His father ran a building firm but died tragically of acute appendicitis when his son was aged 14. Bill intending to pursue the same career entered Leeds University and took a degree in eng...
