Measurement of the hard exclusive $\pi^{0}$ muoproduction cross section at COMPASS / COMPASS Collaboration
A new and detailed measurement of the cross section for hard exclusive neutral-pion muoproduction on the proton was performed in a wide kinematic region, with the photon virtuality $Q^2$ ranging from 1 to 8 (GeV/$c$)$^{\rm\, 2}$ and the Bjorken variable $x_{\rm Bj}$ ranging from 0.02 to 0.45. [...]

Multiplicities of positive and negative pions, kaons and unidentified hadrons from deep-inelastic scattering of muons off a liquid hydrogen target / Alexeev, G.D. (Unlisted) ; Alexeev, M.G.

(Unlisted) ; Augsten, K. (Prague, Tech. U.) ; Augustyniak, W. (NCBJ, Warsaw) ; Azevedo, C.D.R. (Aveiro U.) ; Badelek, B. (Warsaw U.) et al.
The multiplicities of positive and negative pions, kaons and unidentified hadrons produced in deep-inelastic scattering are measured in bins of the Bjorken scaling variable $x$, the relative virtual-photon energy $y$ and the fraction of the virtual-photon energy transferred to the final-state hadron $z$.

High-Statistics Measurement of Collins and Sivers Asymmetries for Transversely Polarized Deuterons / COMPASS Collaboration
New results are presented on a high-statistics measurement of Collins and Sivers asymmetries of charged hadrons produced in deep inelastic scattering of muons on a transversely polarised $^6$LiD target. The data were taken in 2022 with the COMPASS spectrometer using the 160 \gevv muon beam at CERN, balancing the existing data on transversely polarised proton targets. [...]

Final COMPASS results on the transverse-spin-dependent azimuthal asymmetries in the pion-induced Drell-Yan process / COMPASS Collaboration
The COMPASS Collaboration performed measurements of the Drell-Yan process in 2015 and 2018 using a 190 GeV/c $\pi^{-}$ beam impinging on a transversely polarised ammonia target. Combining the data of both years, we present final results on the amplitudes of the five azimuthal modulations in the dimuon production cross section. [...]

Room-Temperature $^{181}$Ta(TiO$_2$): An e-γ TDPAC Study / Yap, Ian Chang Jie (Gottingen U., II. Phys. Inst.) ; Schell, Juliana (CERN ; Duisburg-Essen U.) ; Dang, Thien Thanh (Duisburg-Essen U.) ; Noll, Cornelia (Bonn U., HISKP) ; Beck, Reinhard (Bonn U., HISKP) ; Köster, Ulli (Laue-Langevin Inst.) ; Mansano, Ronaldo (Sao Paulo U.) ; Hofsäss, Hans Christian (Gottingen U., II. Phys. Inst.)
In this work, we report on the hyperfine parameters of the foreign 181Ta probe in the rutile structure of the single crystal TiO2 using the e−γ and γ−γ time differential perturbed angular correlation (TDPAC) technique. We implanted 181Hf ions into a sample of single crystal rutile TiO2 in the Bonn Isotope Separator. [...]

Confirming the Unusual Temperature Dependence of the Electric-Field Gradient in Zn / Haas, Heinz (Aveiro U. ; CERN) ; Zyabkin, Dmitry (Ilmenau Tech.

The electric-field gradient (EFG) at nuclei in solids is a sensitive probe of the charge distribution. Experimental data, which previously only existed in insulators, have been available for metals with the development of nuclear measuring techniques since about 1970. [...]
