Parton Distribution Function sensitivity studies using electroweak processes at LHCb
We describe parton density function sensitivity studies, using muon final
states produced through the Drell-Yan process via W, Z or down to a
Q^2 of 10 GeV^2. This makes use of LHCb's unique ability to trigger on low
transverse momentum objects. Due to the forward acceptance of LHCb, x values
down to 2 10^{-6} can be probed, where with just 100 pb-1 of data, the gluon
PDF can improved up to 70%
TAPAs: A Tool for the Analysis of Process Algebras
Process algebras are formalisms for modelling concurrent systems that permit mathematical reasoning with respect to a set of desired properties. TAPAs is a tool that can be used to support the use of process algebras to specify and analyze concurrent systems. It does not aim at guaranteeing high performances, but has been developed as a support to teaching. Systems are described as process algebras terms that are then mapped to labelled transition systems (LTSs). Properties are verified either by checking equivalence of concrete and abstract systems descriptions, or by model checking temporal formulae over the obtained LTS. A key feature of TAPAs, that makes it particularly suitable for teaching, is that it maintains a consistent double representation of each system both as a term and as a graph. Another useful didactical feature is the exhibition of counterexamples in case equivalences are not verified or the proposed formulae are not satisfied
