1. Hadrons  Arnaud is still working on the note which will
            describe the TPC/CALO selections and give the
            final LEP1 results.
            The note should be ready in a couple of weeks.

2. LUMI     Also the final '95 luminosity note is well in progress.
            Brigitte has produced a large statistics sample at P, P-2
            (KINGAL level) using BHLUMI 4.04.
            The results are perfectly consistent with those obtained
            using the previous version of BHLUMI.
            In the end, the simulation statistical error should be
            reduced from 0.060% down to 0.026%, the theory error
            will go from 0.16% to 0.11% and the total lumi error
            from 0.187% to 0.137%.

            '93 and '94 will also be rerun with the new generator 
            and the correct geometry, to be able to consistently use
            the 0.11% theoretical error.

3.taus      Work is proceeding. The deadline of having
            final or quasi-final results for the next general
            EW meeting (15 november) should be met .
            Gerri will present some results at the EWWG meeting
            of next week. 

4.muons     Andrea has continued his studies on PECO and Gampex
            photons, coming to the conclusion that (contrary to
            what said before) he will use the Gampex photons.
            With this choice, in fact, the background from tau
            pairs is reduced.
            However, the difference between PECO and Gampex energies
            will be used to estimate the systematic uncertainties.
            Andrea has also performed a study of the ITC trigger
            efficiency, by using Bhabha events passing the total energy 
            trigger. The ITC trigger is found to be 100% efficient.

AOB         Following a point raised by Jacques in Clermond,
            it was decided to discuss next week how to treat
            the llV background. Bolek will report on that after
            discussing with the experts (i.e. Manel).
 
            It was also discussed whether the paper should be
            written in the form of a long and detailed paper
            ("Phys.Report style") or in a more compact way.
            It was felt that, since this would be the final LEP1 
            paper on EW results, the first option would be preferable.
            In this case lineshape and asymmetries would be merged
            in a single publication.
            However it clearly implies a lot more work.
            The discussion will continue.

Next meeting: tuesday 22 oct at 14:30 in the small ALEPH room.
