The Higgs boson was postulated nearly five decades ago within the framework of the
standard model of particle physics and has been the subject of numerous searches at …

We report on a precision measurement of low-mass muon pairs in 158 AGeV indium-indium
collisions at the CERN SPS. A significant excess of pairs is observed above the yield …

The NA60 experiment studies muon pair production at the CERN Super Proton Synchrotron.
In this Letter we report on a precision measurement of J/ψ in In-In collisions. We have …

The NA60 experiment at the CERN SPS has studied low-mass muon pairs in 158A GeV In–
In collisions. The mass and pT spectra associated with peripheral collisions can …

The NA60 experiment at the CERN SPS has measured muon pairs with unprecedented
precision in 158 A GeV In–In collisions. A strong excess of pairs above the known sources is …

The yield of muon pairs in the invariant mass region 1< M< 2.5 GeV/c 2 produced in heavy-
ion collisions significantly exceeds the sum of the two expected contributions, Drell-Yan …

The results of the searches for neutral Higgs boson production in the process e+ e−→ Z∗ H0
are reported, focusing on Higgs boson masses below 70 GeV. The data sample consists of …

The formation of the η′ in the reaction e+ e−→ e+ e− η′→ e+ e− π+ π− γ has been
measured by the L3 detector at a centre-of-mass energy of 91GeV. The radiative width of the …

The forward-backward muon detector of the L3 experiment is presented. Intended to be
used for LEP 200 physics, it consists of 96 self-calibrating drift chambers of a new design …

The NA60 experiment at the CERN SPS has studied low-mass dimuon production in 158 A
GeV In-In collisions. An excess of pairs above the known meson decays has been reported …
