Limits on the masses of supersymmetric particles at $\sqrt{s}$ up to 202 GeV

Searches for charginos, neutralinos, sleptons and squarks at LEP2 centre-of-mass energies ($\sqrt{s}$) from 130 GeV to 202 GeV have been used to exclude regions of the MSSM parameter space and to set lower limits on the mass of the Lightest Supersymmetric Particle (LSP) and other supersymmetric particles within the MSSM framework. R-parity conservation has been assumed. The lightest neutralino was found to be heavier than 36.3~\mbox{$ {\mathrm{GeV}}/c^2$} independent of the $m_0$ value. The lightest chargino, the the sneutrino and the right-handed selectron were found to be heavier than 69.5~\mbox{$ {\mathrm{GeV}}/c^2$}, 83.0~\mbox{$ {\mathrm{GeV}}/c^2$}, and 91.0~\mbox{$ {\mathrm{GeV}}/c^2$}, respectively. The results do not depend on $m_0$ and are valid for $1 \le $~tan$\beta \le 40 $, $M_2 \le $~1000~\mbox{${\mathrm{GeV}}/c^2$}, and in the $\mu$ region where the lightest neutralino is the LSP. The effects of mixings in the third family of sfermions are discussed. The confidence level of all limits given is 95\%. If there is no mixing in the stau sector the lightest neutralino has to be heavier than 36.7~\mbox{${\mathrm{GeV}}/c^2$}. In this note the published results %\cite{lsplim} using the data at centre-of-mass energies up to 189~GeV are updated with the data collected by DELPHI in 1999, at centre-of-mass energies up to 202~GeV.
