TL;DR: In this article, an excess of 66±14 (stat.) events were observed in the D∗+π+π−π− final state with a mass of 2637±2(stat.)±6(syst.) MeV/c2 and a full width smaller than 15 MeV /c2 (95% C.L.).

TL;DR: The value of the b quark mass at the M Z scale defined in the MS renormalization scheme was determined using 2.8 million hadronic Z decays collected during 1992-1994 by the DELPHI detector to be m b (M Z )=2.67±0.25 ( stat. )± 0.34 ( frag. )−0.27 ( theo. ) GeV/c 2 ).

TL;DR: A search for stable and long-lived heavy charged particles used the data taken by the DELPHI experiment at energies from 130 to 183 GeV as mentioned in this paper, where the Cherenkov light detected in the Ring ImagingCherenkov D...

TL;DR: In this article, the authors measured trilinear gauge boson couplings using data taken by DELPHI at 161 GeV and 172 GeV, and derived limits on neutral ZVγ couplings from an analysis of the reaction.

TL;DR: The average multiplicity of charged particles in hadronic W decays has been measured for the first time; its value, $19.23 \pm 0.74 (stat+syst)$, is consistent with that expected for an $e^+e^-$ interaction at a centre-of-mass energy equal to the W mass as mentioned in this paper.

TL;DR: In this paper, a multihadronic event recorded at LEP by DELPHI in the years 1992 through 1994, charged hadrons are identified using the measurement of their energy loss and their Cherenkov angle.
9 citations
TL;DR: In this paper, the authors presented results on charged Higgs boson production, based on LEP data collected at √s = 172 GeV, that complement the previous DELPHI results obtained at centre of mass energies up to 161 GeV.

TL;DR: The DELPHI experiment at LEP has measured the inclusive charmless B hadron decay branching ratio, the B branching ratio into two charmed particles, and the total number of charmed particle per B decay, using the hadronic Z data taken between 1992 and 1995 as discussed by the authors.

TL;DR: In this article, a beam test of prototype silicon microstrip detectors and front-end electronics developed for use in the LHC detector ATLAS is reported, where both irradiated and unirradiated modules were measured in a 1.56-T magnetic field for efficiency, noise occupancy, and position resolution as a function of bias voltage, binary hit threshold, and detector rotation angle with respect to the beam direction.
Abstract: Results are reported from a beam test of prototype silicon microstrip detectors and front-end electronics developed for use in the LHC detector ATLAS. The detector assemblies (“modules”) were 12 cm long and were read out with binary electronics. Both irradiated and unirradiated modules were measured in a 1.56 T magnetic field for efficiency, noise occupancy, and position resolution as a function of bias voltage, binary hit threshold, and detector rotation angle with respect to the beam direction.

TL;DR: Two-particle angular correlations in jet cones have been measured in e+e− annihilation into hadrons at LEP energies (View the MathML source 91 and 183 GeV) and are compared with QCD predictions using the LPHD hypothesis as discussed by the authors.

TL;DR: The performance of the silicon strip detector prototypes developed for use in ATLAS at the LHC is reported in this article, where the tracking efficiency, noise occupancy, and position resolution were measured as a function of bias voltage, binary hit threshold, and detector rotation angle in a 156 T magnetic field.
Abstract: The performance of the silicon strip detector prototypes developed for use in ATLAS at the LHC is reported Baseline detector assemblies (“modules”) of 12 cm length were read out with binary electronics at 40 MHz clock speed For both irradiated and unirradiated modules, the tracking efficiency, noise occupancy, and position resolution were measured as a function of bias voltage, binary hit threshold, and detector rotation angle in a 156 T magnetic field Measurements were also performed at a particle flux comparable to the one expected at the LHC
