We show how the LHC potential to detect a rather light CP-even Higgs boson of the NMSSM, H 1 or H 2 , decaying into CP-odd Higgs states, A 1 A 1 , can be improved if Higgs-strahlung off W bosons and (more marginally) off top-antitop pairs are employed alongside vector boson fusion as production modes. Our results should help extracting at least one Higgs… (More)

We study the effects of a possible strong final state interaction among longitudinal W 's in γγ → W W. The relevant partial wave amplitudes are modified by an Omnès function approximated by a Breit-Wigner form factor. We study the fractional cross section f 00 = σ LL /σ Total with both W 's longitudinally polarised, in the presence of a J = 2 resonance (M =… (More)

We have studied dijet production in γγ collisions with a view to probing the physics of large extra dimensions. The exchange of virtual spin-2 Kaluza-Klein excitations is found to modify the dijet cross-section substantially from its Standard Model value and allows the effective string scale to be probed to values between 2.5 and 6.4 TeV in the unpolarised… (More)

We study the process e + e − → W + W − to probe low-scale gravity at high energy linear colliders. A characteristic signature of extra-dimensions models is the forward-backward asymmetry due to the interference of spin-2 graviton and spin-1 SM gauge boson exchange terms, even when right-polarised electron beam is used. Our analysis shows that larger than 5%… (More)
