An investigation on the b quark mass
In this article I will review the measurements of the b quark mass performed
by ALEPH and DELPHI and presented at the HEP99 Conference in Tampere. Very
clean effects of the mass running are observed, even if a wide spread in the
results and large systematic errors due to hadronization corrections prevent to
extract an average value of the running b quark mass.Comment: 3 pages, 1 figure
Recent Results on Heavy Flavours with ALEPH
The latest ALEPH measurements on heavy flavours are presented. In particular
the measurements of V_ub, the B(b -> s gamma) and a study on the width
difference between mass eigenstates in the B_s system are presented.Comment: 7 pages, RevTe
CMS upgrades for SLHC
I will discuss the impact of the LHC luminosity upgrade on CMS detector. While most of the CMS can possibly cope with the increased luminosity, the Tracker must undergo a major redesign in technology both in terms of detector substrates as well as in the data transfer links. I will show the impact on CMS of reduced bunch length and machine elements close to the interaction point
mb from ALEPH and comparison with other LEP experiments
I will review the measurements of the -quark mass performed by ALEPH and
DELPHI. A large set of observables has been used together with detailed studies
on jet algorithms. Very clear effects due to the -quark mass running are
observed. Comparing with the determinations at the threshold,
the measurements of the running -quark mass at the pole are consistent
with the predicted evolution from QCD.Comment: 10 pages, 7 figures, submitted to QCD2000, Montpellier, Franc
