Two new bands have been identified in 137Nd from a high-statistics JUROGAM II gamma-ray spectroscopy experiment. Constrained density functional theory and particle rotor model calculations are used to assign configurations and investigate the band properties, which are well described and understood. [...]

(Liverpool U.) et al.
The electron spectrometer, SPEDE, has been developed and will be employed in conjunction with the Miniball spectrometer at the HIE-ISOLDE facility, CERN. SPEDE allows for direct measurement of internal conversion electrons emitted in-flight, without employing magnetic fields to transport or momentum filter the electrons. [...]

Evidence against the wobbling nature of low-spin bands in 135Pr / Lv, B.F. (Lanzhou, Inst. Modern Phys. ; Beijing, GUCAS) ; Petrache, C.M. (IJCLab, Orsay) ; Lawrie, E.A.

Modern Phys. ; Beijing, GUCAS) et al.
The electromagnetic character of the ΔI=1 transitions connecting the one- to zero-phonon and the two- to one-phonon wobbling bands should be dominated by an E2 component, due to the collective motion of the entire nuclear charge. In the present work it is shown, based on combined angular correlation and linear polarization measurements, that the mixing ratios of all analyzed connecting transitions between low-lying bands in 135Pr interpreted as zero-, one-, and two-phonon wobbling bands, have absolute values smaller than one.

Study of radial motion phase advance during motion excitations in a Penning trap and accuracy of JYFLTRAP mass spectrometer / Nesterenko, D.A. (Jyvaskyla U.) ; Eronen, T. (Jyvaskyla U.) ; Ge, Z. (Jyvaskyla U.) ; Kankainen, A. (Jyvaskyla U.) ; Vilen, M. (Jyvaskyla U. ; CERN)
Phase-imaging ion-cyclotron-resonance technique has been implemented at the Penning-trap mass spectrometer JYFLTRAP and is routinely employed for mass measurements of stable and short-lived nuclides produced at IGISOL facility. Systematic uncertainties that impose limitations on the accuracy of measurements are discussed. [...]

The MORA project / MORA Collaboration
The MORA (Matter's Origin from the RadioActivity of trapped and oriented ions) project aims at measuring with unprecedented precision the D correlation in the nuclear beta decay of trapped and oriented ions. The D correlation offers the possibility to search for new CP-violating interactions, complementary to searches done at the LHC and with Electric Dipole Moments. [...]

Quantum transport and the phase space structure of the Wightman functions / Jukkala, Henri (Jyvaskyla U. ; Helsinki U.) ; Kainulainen, Kimmo (Jyvaskyla U. ; Helsinki U. ; CERN) ; Koskivaara, Olli (Jyvaskyla U. ; Helsinki U.)
We study the phase space structure of exact quantum Wightman functions in spatially homogeneous, temporally varying systems. In addition to the usual mass shells, the Wightman functions display additional coherence shells around zero frequency k0=0, which carry the information of the local quantum coherence of particle-antiparticle pairs.

A QCD analysis of LHCb D-meson data in p+Pb collisions / Eskola, Kari J. (Helsinki U. ; Jyvaskyla U.) ; Helenius, Ilkka (Helsinki U. ; Jyvaskyla U.) ; Paakkinen, Petja (Helsinki U. ; Jyvaskyla U.) ; Paukkunen, Hannu (Helsinki U. ; Jyvaskyla U.)
We scrutinize the recent LHCb data for D0-meson production in p+Pb collisions within a next-to-leading order QCD framework. Our calculations are performed in the SACOT-mT variant of the general-mass variable-flavour-number scheme (GM-VFNS), which has previously been shown to provide a realistic description of the LHC p+p data.

Nuclear moments of indium isotopes reveal abrupt change at magic number 82 / Vernon, A R (Manchester U. ; MIT ; Leuven U.) ; Garcia Ruiz, R F (MIT ; CERN) ; Miyagi, T (TRIUMF) ; Binnersley, C L (Manchester U.) ; Billowes, J (Manchester U.) ; Bissell, M L (Manchester U.) ; Bonnard, J (York U., England) ; Cocolios, T E (Leuven U.) ; Dobaczewski, J (York U., England) ; Farooq-Smith, G J (Leuven U.) et al.
In spite of the high-density and strongly correlated nature of the atomic nucleus, experimental and theoretical evidence suggests that around particular ‘magic’ numbers of nucleons, nuclear properties are governed by a single unpaired nucleon1,2. A microscopic understanding of the extent of this behaviour and its evolution in neutron-rich nuclei remains an open question in nuclear physics35. [...]

QCD Challenges from pp to A-A Collisions / Adolfsson, J. (Lund U.) ; Andronic, A. (Munster U.) ; Bierlich, C. (Lund U. ; Bohr Inst.) ; Bozek, P. (AGH-UST, Cracow) ; Chakraborty, S.

This paper is a write-up of the ideas that were presented, developed and discussed at the third International Workshop on QCD Challenges from pp to A-A, which took place in August 2019 in Lund, Sweden. The goal of the workshop was to focus on some of the open questions in the field and try to come up with concrete suggestions for how to make progress on both the experimental and theoretical sides.
