T-parity, its problems and their solution

Alessandro Vichi, Duccio Pappadopulo

We point out a basic difficulty in the construction of little-Higgs models with T-parity which is overlooked by large part of the present literature. Almost all models proposed so far fail to achieve their goal: they either suffer from sizable electroweak ...

Anomaly driven signatures of new invisible physics at the Large Hadron Collider

Alexey Boyarsky, Oleg Ruchayskiy

Many extensions of the Standard Model (SM) predict new neutral vector bosons at energies accessible by the Large Hadron Collider (LHC). We study an extension of the SM with new chiral fermions subject to non-trivial anomaly cancellations. If the new fermio ...

Automation of next-to-leading order computations in QCD: the FKS subtraction

We present the complete automation of the universal subtraction formalism proposed by Frixione, Kunszt, and Signer for the computation of any cross section at the next-to-leading order in QCD. Given a process, the only ingredient to be provided externally ...

Search for an invisibly-decaying Higgs boson at LEP

Qian Wang, Aurelio Bay, Horst Vogel, Eduardo Sanchez, Zhirui Xu, Werner Lustermann, Liang Sun, Jian Zhao, Ji Hyun Kim, Zheng Wang, Matthias Weber, Xiao Wang

A search for a Higgs boson produced in e(+)e(-) collisions in association with a Z boson and decaying into invisible particles is performed. Data collected at LEP with the U detector at centre-of-mass energies from 189 to 209 GeV are used, corresponding to ...

Minimal gauge-Higgs unification with a flavour symmetry

Claudio Scrucca

We show that a flavour symmetry a la Froggatt-Nielsen can be naturally incorporated in models with gauge-Higgs unification, by exploiting the heavy fermions that are anyhow needed to realize realistic Yukawa couplings. The case of the minimal five-dimensio ...

Measurement of the cross section of W-boson pair production at LEP

Aurelio Bay

The cross section of W-boson pair-production is measured with the L3 detector at LEP. In a data sample corresponding to a total luminosity of 629.4 pb-1, collected at centre-of-mass energies ranging from 189 to 209 GeV, 9834 four-fermion events with W boso ...

Study of the e+e-→Zγ process at LEP and limits on triple neutral-gauge-boson couplings

Aurelio Bay

The process e+e-→Zγ where the Z boson decays into hadrons or neutrinos, is studied with data collected with the L3 detector at LEP at centre-of-mass energies from 189 up to 209 GeV. The cross sections are measured and found to be in agreement with the Stan ...

Search for branons at LEP

Aurelio Bay

We search, in the context of extra-dimension scenarios, for the possible existence of brane fluctuations, called branons. Events with a single photon or a single Z-boson and missing energy and momentum collected with the L3 detector in e+e- collisions at c ...

Study of the e+e- → Ze+e- process at LEP

Aurelio Bay

The cross section of the process e+e- → Ze+e- is measured with 0.7 fb-1 of data collected with the L3 detector at LEP. Decays of the Z boson into quarks and muons are considered at centre-of-mass energies ranging from 183 GeV up to 209 GeV. The measurement ...

Theories with gauge-mediated supersymmetry breaking

Riccardo Rattazzi

Theories with gauge-mediated supersymmetry breaking provide an interesting alternative to the scenario in which the soft terms of the low-energy fields are induced by gravity. These theories allow for a natural suppression of flavour violations in the supe ...
