K/sup -/-meson absorptions at rest in carbon nuclei leading to final states containing a Lambda -hyperon / Van der Velde-Wilquet, C ; Comber, C ; Davis, D H ; Sacton, J ; Tovee, D N ; Wickens, J H
A study has been made of K/sup -/-meson interactions at rest in the CERN 1.1 m/sup 3/ heavy-liquid bubble chamber filled with a mixture of hydrocarbons. The emission frequency of Lambda /sup 0/-hyperons following K/sup -/-meson absorptions in carbon nuclei is determined to be 0.68+or-0.02. [...]

The conversion probability and emission ratio of charged Sigma - hyperons following K/sup -/ meson capture at rest in carbon / Van der Velde-Wilquet, C ; Keyes, G S ; Sacton, J ; Wickens, J H
A study has been made of K/sup -/ meson interactions at rest in the CERN 1.1 m/sup 3/ heavy liquid bubble chamber filled with a mixture of hydrocarbons. The data are used to determine (i) the internal conversion probability, C( Sigma /sup -/), of Sigma /sup -/ hyperons produced in association with pi /sup +/ mesons by K/sup -/ meson interactions in carbon nuclei, (ii) the relative emission frequencies of ( Sigma /sup +/ pi /sup +/) and ( Sigma /sup -/ pi /sup +/) pairs, E( Sigma /sup +/ pi /sup +// Sigma /sup -/ pi /sup +/), and the emission frequency E( Sigma /sup +or-/ pi /sup -or+//K/sup -/), of ( Sigma /sup +or-/ pi /sup -or+/) pairs per K/sup -/ meson absorption in carbon, (iii) the branching fraction, P( Sigma /sup -/ pi /sup +//K /sup -/), for the primary process K/sup -/+p to Sigma /sup -/+ pi /sup +/ in carbon and (iv) the trapping probability, T( Lambda /sup 0/), for Lambda /sup 0/ hyperons produced by Sigma /sup -/ hyperon interactions in carbon nuclei.

The measurement of $\alpha_s$ from event shapes with the DELPHI detector at the highest LEP energies / DELPHI Collaboration
Hadronic event shape distributions are determined from data in e+e- collisions between 183 and 207 GeV. From these the strong coupling alpha_s is extracted in O(alpha_s^2), NLLA and matched O(alpha_s^2)+NLLA theory. [...]

Search for Charged Higgs Bosons in $e^{+} e^{-}$ Collisions at $\sqrt{s}$=189-202 GeV / DELPHI Collaboration
A search for pair-produced charged Higgs bosons was performed in the high energy data collected by the DELPHI detector at LEP II at centre-of-mass energies from 189~GeV to 202~GeV\@. The three different final states, $\tau \nu \tau \nu$, $c \bar s \bar c s$ and $c \bar s \tau \nu$ were considered. [...]

Measurement of the semileptonic b branching fractions and average b mixing parameter in Z decays / DELPHI Collaboration
The semileptonic branching fractions for primary and cascade b decays BR(b -> lepton-), BR(b -> c -> lepton+) and BR(b -> cbar -> lepton-) were measured in hadronic Z decays collected by the DELPHI experiment at LEP. The sample was enriched in b decays using the lifetime information and various techniques were used to separate leptons from direct or cascade b decays [...]

Single Intermediate Vector Boson Production in $e^+ e^-$ collisions at $\sqrt{s}$ = 183 and 189 GeV / DELPHI Collaboration
The cross-sections for the production of single charged and neutral intermediate vector bosons were measured using integrated luminosities of 52~pb$^{-1}$ and 154~pb$^{-1}$ collected by the DELPHI experiment at centre-of-mass energies of 182.6~GeV and 188.6~GeV, respectively. The cross-sections for the reactions were determined in limited kinematic regions. [...]
