Polish contribution to fixed target experiments
Higher luminosity
pT range starting from 0 MeV/c
Rapidity coverage (in most cases full forward
range) → possibility to obtain 4 spectra
For A+A → forward E and centrality determination
Polarized DIS (i.e. with e or polarized beams)
presently possible only in the FT mode

1st meas. of Sivers asymm. for gluons using SIDIS (NCBJ)
Hardware involvement (PW):
● So far: Scintillating fiber detector, 2 planes, 192 channels each; Front-end electronics for ECAL0
cal. - amplifiers for silicon photomultipliers, part of trigger electronics; Small scintillating fiber detector
for use in test beams; Active HV dividers for supplying photomultipliers of the CAMERA detector
● Current: Upgrade of CEDAR detectors (HV supply for PMTs, front-end electronics, project
coordination), to be used also in the AMBER experiment
● Planned: Algorithms for and implementation of feature extraction algorithms for system with full sampling of waveforms
(time & charge estimation). Required for trigerless readout; data reduction is needed, as current data stream is too large
Current funding – grants from Polish National Science Centre:
● Consortium (NCBJ, UW, PW) “Harmonia” grant for data taking, “Common Found” and analysis (2018-
2020, 0.78 MPLN). Problems: limited funding makes it impossible to send students to practice at the experiment
● 1 just finished “Opus” grant for analysis and upgrade of CEDAR detectors (PW, 2017-2019, 0.43 MPLN)

Planned elastic +e scattering experiment at CERN SPS; a high intensity muon beam
at 150 GeV/c (se=0.4 GeV) would be suited for the measurement. Experiment
dedicated to measure a hadronic correction to the anomalous muon magnetic
moment (g-2)→ in order to increase sensitivity to the potential New Physics
phenomena which may cause an observed discrepancy with respect to the
Standard Model predictions. Contribution from hadronic vacuum polarization is one of the two
dominant sources of theoretical uncertainty
Detector: long segmented target made of thin Be planes
Hadronic correction should equipped with high precision Silicon trackers, followed by
be measured with precision EM calorimeter and muon detector

produce useful result

Informal research group consisted of experimentalists and theoreticians promoting a
science case for a fixed-target experiment using LHC beams: 7 TeV proton and
2.76 TeV lead beams (sNN= 115 GeV and 72 GeV); luminosity higher than at RHIC
Physics case:
Advance understanding of high-x gluons, antiquark and heavy-quark content in
the nucleon & nucleus
Dynamics and spin of gluons and quarks inside polarized and unpolarized nucleons
Heavy-ion collisions towards large rapidities
Exclusive and semi-exclusive processes → ultra-peripheral collisions in fixed-
target mode, diffractive hadrons production / heavy baryon production

RECFA Warsaw May 24th 2019 Polish contribution to fixed target experiments K. Grebieszkow 33Summary
Polish Fixed Target community is active and well visible in operating and planned
experiments at JINR, GSI, CERN, and BNL
In almost all experiments we have (had) significant contribution to hardware and
(plans for) data analysis; we also contribute (usually not mentioned on slides) to
software development (calibration, reconstruction, database, etc.)
*) R (%) = (seniors + PhD students) / author list or www
**) Author list (or web page) not necessarily reflects the real contribution to the project, especially in case of ending
(FOPI) or planned experiments
***) Students are usually not included in the author list
RECFA Warsaw May 24th 2019 Polish contribution to fixed target experiments K. Grebieszkow 34Summary
Hardware for FAIR (CBM and PANDA) and JINR experiments will be (is) mostly funded from
the Polish financial contributions to FAIR and JINR (HADES ECal from MSHE grant).
NA61 and COMPASS hardware upgrades are financed mainly via NSC grants. Data
analysis in ongoing experiments is mostly financed by NSC grants.
Problems:
No stable, long-term support (10-15 years ?) for planned experiments
Funds in NSC grants are limited (for example 1.5 MPLN in just closed "Harmonia" grants) which is
problematic for consortia involving many institutions
No dedicated resources for young students to send them for practicing at the experiment; very
important in view of decreasing number of heavy ion and particle physics students
