Welcome to the COMPASS MaNTRA (MeAsurements of Nucleon Transversity) Project page.
The primary goal of this project is to identify unambiguous transverse spin and transverse momentum phenomena of the nucleon trhough the study of asymmetries in SIDIS of high-enervy leptons on transversely polarised proton and deuteron targets.
The project aims at finally obtaining a global analysis of transversity and of its related observables, in order to acheive the creation of a general and homogenuous framework, including the different processes that directly or indirectly measure different combinations of the transverse-spin distribution and fragmentation functions.

This page is the starting point from where a number of pieces of information can be collected about this project, its achievements and status.
Also, a data repository information service is provided, for the convenience of the scientists who need to get them quickly & easily to use them in their own analysis.
