A new precise measurement of \V-cb\ and of the branching ratio BR(<(Bover bar>(0)--> D(+*)l(-)<(<nu>)over bar>(l)) has been performed using a sample of about 5000 semileptonic ...decays (B) over bar (0) --> D(*+)l(-)<(<nu>)over bar>(l), selected by the DELPH
A test of the QED process e(+)e(-) --> gamma gamma>(*) over bar *(gamma) is reported. The data analysed were collected with the DELPHI detector in 1998 and 1999 at the highest energies achieved ...at LEP, reaching 202 GeV in the centre-of-mass. The total int
A study of b semileptonic decays into D, D pi(+/-) and D*pi(+/-) final states is presented. The D-0, D+ and D*(+) mesons are exclusively reconstructed in Z decay data recorded from 1992 to 1995 in ...the DELPHI experiment at LEP. The overall branching fracti
The DELPHI detector at LEP has collected 54 pb(-1) of data at a centre-of-mass energy around 183 GeV during 1997, 158 pb(-1) around 189 GeV during 1998, and 187 pb(-1) between 192 and 200 GeV during ...1999. These data were used to measure the average charge
The branching ratio for the leptonic decay of charged B mesons (B- --> tau (-)<(<nu>)over bar>(tau)) has been measured using selected leptonic tau (-) --> l(-)nu ...(tau)<(<nu>)over bar>(l) and hadronic tau (-) --> nu X-tau decays in Z --> b (b) over bar dec
Data collected at the Z resonance using the DELPHI detector at LEP are used to determine the charged hadron multiplicity in gluon and quark jets as a function of a transverse momentum-like scale. The ...colour factor ratio, C-A/C-F, is directly observed in t
A search for unstable heavy fermions with the DELPHI detector at LEP is reported. Sequential and non-canonical leptons, as well as excited leptons and quarks, are considered. The data analysed ...correspond to an integrated luminosity of about 48 pb(-1) at a
The total and the differential cross-sections for the reaction e(+)e(-) --> gamma gamma(gamma) have been measured with the DELPHI detector at LEP at centre-of-mass energies from 130 to 183 GeV for ...an integrated luminosity of 78.19 pb(-1). The results agre
The data collected by DELPHI in 1996 have been used to measure the average charged particle multiplicities and dispersions in q (q) over bar events at centre-of-mass energies of root s = 161 GeV and ...root s = 172 GeV, and the average charge multiplicity in
The hadronic structure of the decay of the tau lepton to three charged particles, tau --> 3 pi nu(tau), is studied using data collected by the DELPHI detector at LEP between 1992 and 1995. The ...invariant mass of the 3 pi system, m(3 pi), is fitted using th
