Lectures on Jump Systems Lectures on Jump Systems

This document contains notes that accompanied a series of four lectures on jump systems. These lectures were presented at the Center of Parallel Computing to an audience consisting mainly of graduate students. Abstract A jump system is a nonempty set of integral vectors that satisfy a certain exchange axiom. of Lovv asz. A degree system of a graph G is the set of degree sequences of all subgrap...

The COMPASS future: COMPASS II

Up to now the COMPASS experiment [1] contributed with the muon beam to precise measurements of the nucleon longitudinal momentum structure. A more complete nucleon description beyond collinear approximation includes the quark intrinsic momentum distributions which are described by the Transverse Momentum Dependent (TMD) Parton Distribution Functions (PDFs) and by Generalised Parton Distribution...

COMPASS results on gluon polarisation

One of the missing keys in the present understanding of the spin structure of the nucleon is the contribution from the gluons: the so-called gluon polarisation. This quantity can be determined in DIS through the Photon-Gluon Fusion (PGF) process, in which two analysis methods may be used: (i) identifying open charm events or (ii) selecting events with high-p T hadrons. The data used in the pres...

Compass routing on geometric networks

Suppose that a traveler arrives in the city of Toronto, and wants to walk to the famous CN Tower, one of the tallest free-standing structures in the world. Our visitor, lacking a map of Toronto, is standing at an intersection fromwhich he can see the CN Tower, and several streets S1; : : : ; Sm from which he can choose to start his walk. A natural (and most likely safe) assumption is that our v...
