5 TMD evolution from SIDIS data

TMD evolution from SIDIS data (25' + 5')

Abstract:
Obtaining information on transverse momentum dependent functions (TMDs) from data has tested our understanding of the underlying theory of strong interactions. At small to moderate values of the hard scale, it is of particular importance to make at least rough estimates of the applicability of factorization theorems. In this talk, I will discuss about how one may try to address this issue in SIDIS. I wil focus on the unpolarized case, providing concrete examples of the challenges currently faced in the extraction of TMDs.

10 Generalised Parton Distribution studies through Deeply Virtual Compton Scattering at Jefferson Lab

Generalised Parton Distribution studies through Deeply Virtual Compton Scattering at Jefferson Lab (25' + 5')

Abstract:
Generalised Parton Distributions (GPDs), which relate the longitudinal momentum fraction of quarks and gluons to their transverse position, enable 3D tomographic imaging of the nucleon and can provide information on its spin composition and distribution of pressure. The golden channel for accessing GPDs experimentally is the exclusive process of deeply virtual Compton scattering (DVCS), in which a high energy electron scatters from a parton within a nucleon and a high energy photon is produced as a result. We present DVCS highlights from Jefferson Lab in the 6 GeV era and an overview of the 12 GeV programme.

13 Experiment GlueX: Early results and future plans

Experiment GlueX: Early results and future plans (25' + 5')

Abstract:
The GlueX experiment in Hall D at Jefferson Lab has just finished the data taking for the first phase of the project. The main purpose of the experiment is the search for hybrid mesons in the light quark sector. The experiment studies interactions of a linearly polarized photon beam made by 11.7 GeV electrons with a hydrogen target, with the help of a nearly hermetic spectrometer for charged and neutral particles. About 25% of the data acquired have been analyzed. The first physics results include studies of photoproduction of light mesons by a linearly polarized beam, and a measurement of the J/psi photoproduction close to threshold. The latter allows to search for the LHCb's pentaquarks in photoproduction. The first results on the search for hybrid mesons are expected after the whole data sample has been analyzed. The next stage of GlueX data taking will include a new detector for charged kaon identification, and will run at higher luminosity, in order to search for hybrid mesons decaying to strange particles, as well as to contribute to the spectroscopy of hyperons. I will also discuss a proposal to modify the Hall D facility in order to provide a K0L beam, which would allow to study strange baryons and mesons at a new level of precision.

22 The Data Acquisition System for the COMPASS++/AMBER Experiment

The Data Acquisition System for the COMPASS++/AMBER Experiment (25' + 5')

Abstract:
COMPASS++/AMBER experiment is a multipurpose spectrometer at the CERN SPS. It will perform variety of measurements with different beams and targets addressing fundamental questions of Quantum Chromodynamics. The development of the data acquisition is challenged by diverse requirements of wide physics programs, difference in detectors compositions, and high precision measurements i.e. high statistics and high data rate. In order to be flexible and be able to cope with high data rate, the new DAQ employs trigger less free running front-end electronics. Depending on the physics program the amount of data streamed by the detectors may exceed 30 GB/s during the spill. A data reduction is performed by an integrated digital trigger processor, which defines a time of interest. The data within the time of interest are extracted, merged in one event, and transmitted to the Central Data Recording facility. The bandwidth of the CDR is limited to 2 GB/s.
The architecture of the DAQ and the state of the development will be presented.
