Project GDH&SPASCHARM
Yu.Usov
A.Kovalik
Study of the nucleon spin structure in strong and electromagnetic interactions
The main JINR contribution consists in
development, construction and maintenance
of the polarized targets for spin studies at the
accelerators MAMI (Mainz) and U-70 in Protvino.
Both transverse and longitudinal polarization of
protons or deuterons is provided in the
frozen-spin target with a maximum polarization
90% for protons and 80% for deuterons.

target development and construction.

Within two last years, many new data on
polarization observables in the processes of p0
and h-meson production, Compton scattering
have been obtained, and a flow of new results
is expected.
The measurements have been done with
circular (linear) polarized photon beams and
transversal (longitudinal) polarized target.
Spin polarizability of proton from the measurement
of the Compton scattering asymmetry in the
region of D(1232) resonance.
Double polarization observable E for gp  ph
and gn  nh
In the subproject SPASCHARM in Protvino
the setup is under preparation for physics
measurements.
The achieved target polarization is
above 90% for protons.

Investigation of near-threshold p-meson production,
pp{pp}sp0, pn{pp}sp -, in the single and double
polarization modes made it possible to fulfill the
partial wave analysis in order to clarify the role of
the contact operator important in the chiral
perturbation theory.

In total, only within the last years experimental results of ANKE were published
in 15 papers (in Phys.Lett.B, Phys.Rev.C, Eur.Phys.Jour.A),
in many of them the contribution of JINR is decisive.
At ANKE there were prepared 6 diploma and 3 PhD theses, 2 more PhD are close
to finalizing, ANKE results were partly used in 3 doctoral theses.
Since 2015 operation of COSY for hadron physics has been terminated
and ANKE is now dismantled.

But there is a lot of data collected in the last decade still not analyzed.
Therefore, we are planning to continue data analysis.
ANKE+COSY is a unique on the world-wide scale complex
for spin studies at intermediate energies, and one has to extract
as much as possible information from the collected data.

Results
Another part of SPRING is preparation for
the PAX experiment aimed at studies with
polarized antiprotons.
Spin-filtering method for polarization of the beam
has been tested in 2012-2014 and the experimental
result agrees with the theoretical prediction
(building up of the transversal polarization).

Beam measurements on the PAX program
could be continued when the Siberian snake
is implemented in the COSY ring.
This would test the spin-filtering method for
longitudinal polarization.

Observation of EDM is possible via detection of
a tiny polarization arising in an initially unpolarized beam.
As a consequence, the experiment makes very high demands
to accelerator performance in terms of beam lifetime,
polarization lifetime and other beam parameters.

The DLNP JINR group successfully fulfilled R&D
in order to update the developed in VBLHEP
technology for production of very thin straw tubes
required in COMET.
As a result, a complete set of thin-wall (20m)
tubes of 9.8 mm diameter has been produced
in 2015 for Phase-1 of the experiment
(> 2700 tubes) and delivered to Japan for
the detector assembling
For Phase-2 even thinner (12m) and less
diameter tubes (ᴓ 5 мм) are required.
With this aim new R&D studies should be done
by the JINR-COMET group.

In order to select the crystal type for ECAL,
tests of the calorimeter prototypes
with the LYSO and GSO crystals
were carried out in 2014 at the electron
beam of the accelerator in Tohoku with
our participation.
Data analyses fulfilled independently
in Japan and Dubna have demonstrated
the advantages of the LYSO type
which finally was selected as the type
to be used in the calorimeter.
A new test bench has been prepared
in DLNP for tests of the crystals.

Experiment TRITON
D.Demin
Experiment TRITON at Phasotron DLNP studies
the nuclear fusion reactions in the ptµ system.
Systematic studies of the muon catalysis have
started in Dubna since 1964 and stimulated
research activity in this field in many laboratories
all over the world.
Among different muon catalysed reactions
(pd, dd, dt, tt, pt) only in the pt-fusion
a strong disagreement between experimental
yields (in a single measurement of PSI, 1993) and
theoretical predictions was observed.
Project TRITON was proposed by DLNP in 2011
in order to resolve this problem.
ptμ = 4Heμ + γ + 19,82 MeV (Eγ = 19.77 MeV), (1)
ptμ = 4He + μ + 19,81 MeV (Eμ = 19.22 MeV, (2)

Preliminary results of the May run presented
at the previous PAC meeting
 The yields of the channels with emission of a single gamma ptμ = 4Heμ +γ+19,82 MeV
or a muon ptμ = 4He +μ +19,81 MeV agree with the results of the PSI group.
Thus, contradiction with theory still remains.
 For the first time in the pt-fusion reaction, the channel with emission of e+e- pairs
was detected:
ptμ = 4Heμ + e+ + e– + 18,79 MeV
The yield is compatible with the theoretical predictions of Ya.B. Zel'dovich and
S.S. Gershtein (1960) for this channel.
 For the first time an indication was obtained to existence of a new reaction channel
with emission of a pair of gammas: ptμ = 4Heμ + γ + γ + 19,82 MeV

Following the PAC recommendation, in November 2016 another beam
measurements were fulfilled with a different tritium concentration
(0.08% tritium in the T/H mixture) and in two different detector geometries
Results (preliminary!) of the November run:
1. Predictions about the dependence of the reaction yield
on the tritium concentration have been confirmed.
2. Existence of a new reaction channel with emission
of two gamma-quanta has been confirmed.
3. Measurements with different detector geometries
have shown existence of an angular correlation of
the e+ and e- emission, and an absence of such
correlation in emission of two gammas.
This allows to make conclusions about the transition
type.

Experiment MEG-PEN
N.Kuchinsky
MEG-PEN – high precision study of rare and
forbidden decays of muons and pions.
The decays p+  e+n и m+  е+ g have been studied at the
setups PIBETA and MEG (PSI), respectively. The data taking
is finished, and analysis is in progress.
JINR has made a large contribution in the setup PIBETA:
cylindrical proportional chambers with electronics,
CsI crystals, miniature time projection chamber (mTPC)
developed in JINR especially for this experiment.
For MEG the drift chambers have been constructed with
the JINR participation.

Data analysis on the decay p+  e+n where JINR is actively participating
is close to finishing. A total statistics amounts to 2.3∙107 events.
The final results on this decay are foreseen in the first half of 2017.
The expected relative precision is ΔBR/BR ≈ 5·10-4
 5 times improvement.
In 2016 two papers were published on measurement
Pµ = −0.86 ± 0.02 (stat) +0.05 -0.06 (syst)
of the muon beam polarization,
and the branching ratio of the muon radiative decay,
BR(m→enenmg) = (6.03±0.14stat±0.53sys)×10−8.
These data were necessary for obtaining the final result for the decay m+  е+g.
Using a full collected statistics,
new upper limit of m+  е+g decay has been established, BR(µ+ → e+γ) < 4.2 × 10−13 .
This result improves the previous value of the same group by a factor ~1.4.
