MSSM SUGRA searches at LEP
Author(s) :
Alderweireld, T.
Description :
During the LEP2 operation, the 4 LEP experiments have collected data at
centre-of-mass energies up to 209 GeV. Those data have been analysed in the
search of charginos, neutralinos and sfermions in the framework of the Minimal
Supersymmetric Standard Model (MSSM) with R-parity conservation and ass...

Search of AMSB with the DELPHI data
Author(s) :
Alderweireld, T.
Description :
The data collected by the DELPHI experiment up to the highest LEP2 energies
were used to put constraints on the Anomaly Mediated SUSY Breaking model with a
flavour independent m0 parameter. The experimental searches covered several
possible signatures experimentally accessible at LEP, with either ...

Detailed empirical study of the term structure of interest rates. Emergence of power laws and scaling laws
Description :
The technique of Pad´e Approximants, introduced in a previous work, is applied to
extended recent data on the distribution of variations of interest rates compiled by the
Federal Reserve System in the US. It is shown that new power laws and new scaling
laws emerge for any maturity not only as a func...

Description :
A test of the benchmark QED process e(+) e(-) →gammagamma(gamma) is reported, using the data collected with the DELPHI detector at LEP 2. The data analysed were recorded at centre-of-mass energies ranging from 161 GeV to 208 GeV and correspond to a total integrated luminosity of 656.4 pb(-1). The Bo...

Description :
The tau lepton lifetime has been measured with the e(+) e(-) → tau(+) tau(-) events collected by the DELPHI detector at LEP in the years 1991 - 1995. Three different methods have been exploited, using both one-prong and three-prong tau decay channels. Two measurements have been made using events in ...

Description :
The production fractions of charged and neutral b-hadrons in b- quark events from Z(0) decays have been measured with the DELPHI detector at LEP. An algorithm has been developed, based on a neural network, to estimate the charge of the weakly- decaying b-hadron by distinguishing its decay products f...

Description :
The standard method used for tagging b-hadrons in the DELPHI experiment at the CERN LEP Collider is discussed in detail. The main ingredient of b-tagging is the impact parameters of tracks, which relies mostly on the vertex detector. Additional information, such as the mass of particles associated t...

Description :
DELPHI results are presented on the inclusive production of two (K(K) over bar π)(0) states in the mass region 1.2-1.6 GeV/c(2) in hadronic Z decays at LEP I. The measured masses (widths) are 1274 +/- 6 MeV/c(2) (29 +/- 12 MeV/c(2)) and 1426 +/- 6 MeV/c(2) (51 +/- 14 MeV/c(2)), respectively. A parti...

Description :
A search for pair-produced doubly charged Higgs bosons has been performed using the data collected by the DELPHI detector at LEP at centre-of-mass energies between 189 and 209 GeV. No excess is observed in the data with respect to the Standard Model background. A lower limit for the mass of 97.3 GeV...
