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...
متن کاملCompass ∗
The nucleon spin structure is studied at COMPASS via the measurement of the spin dependent properties of deep inelastic muon-deuteron scattering. Both inclusive and semi-inclusive observables are investigated, with the emphasis put on the latter. This allows to access, in particular, the gluon polarization (∆G/G) and the flavor decomposition of the quark helicity distributions. Results from mea...
متن کاملThe COMPASS - II program
Research Board. The proposal consists of three main parts: 1) nucleon structure study via DrellYan process using a negative pion beam and transversely polarized proton target 2)nucleon structure study in exclusive positive and negative muon beam scattering off the unpolarized proton target 3)test of the chiral perturbative theory predictions via reactions of Primakoff scattering using hadron beam.
متن کاملThe COMPASS Location System
The aim of COMPASS (short for COMmon Positioning Architecture for Several Sensors) is to realize a location infrastructure which can make use of a multitude of different sensors and combine their output in a meaningful way to produce a so called Probability Distribution Function (PDF) that describes the location of a user or device as coordinates and corresponding location probabilities. Furthe...
متن کاملThe sun compass revisited
Many animals, and birds in particular, are thought to use directional information from the sun in the form of a time-compensated sun compass, with predictably deviated orientation under clock shift being regarded as the litmus test of this. We suggest that this paradigm obscures a number of other ways in which solar-derived information could be important in animal orientation. We distinguish be...
