The θ-angle and axion physics of two-color QCD at fixed baryon charge
/ Bersini, Jahmall (Boskovic Inst., Zagreb) ; D'Alise, Alessandra (Naples U. ; INFN, Naples) ; Sannino, Francesco (Southern Denmark U., CP3-Origins ; SSM, Naples ; Naples U. ; INFN, Naples ; CERN) ; Torres, Matías (Naples U. ; INFN, Naples)
We analyze the impact of the $\theta$-angle and axion dynamics for two-color (in fact any $Sp(2N)$) QCD at nonzero baryon charge and as a function of the number of matter fields on the vacuum properties, the pattern of chiral symmetry breaking as well as the spectrum of the theory. We show that the vacuum acquires a rich structure when the underlying $CP$ violating topological operator is added to the theory. [...]

Resonant laser ionization and mass separation of $^{225}$Ac
/ Johnson, Jake D (Leuven U.) ; Heines, Michael (Leuven U.) ; Bruchertseifer, Frank (Geel, JRC) ; Chevallay, Eric (CERN) ; Cocolios, Thomas E (Leuven U.) ; Dockx, Kristof (Leuven U.) ; Duchemin, Charlotte (Leuven U. ; CERN) ; Heinitz, Stephan (SCK-CEN, Mol) ; Heinke, Reinhard (Leuven U. ; CERN) ; Hurier, Sophie (Leuven U. ; SCK-CEN, Mol) et al.
$^{225}$Ac is a radio-isotope that can be linked to biological vector molecules to treat certain distributed cancers using targeted alpha therapy. However, developing $^{225}$Ac-labelled radiopharmaceuticals remains a challenge due to the supply shortage of pure $^{225}$Ac itself. [...]

Uncertainty analysis of polymer-based capacitive relative humidity sensor at negative temperatures and low humidity levels
/ Kapić, Amar (Ecole Polytechnique, Lausanne ; CERN) ; Tsirou, Andromachi (CERN) ; Verdini, Piero Giorgio (CERN ; INFN, Pisa) ; Carrara, Sandro (Ecole Polytechnique, Lausanne)
Capacitive relative humidity sensors, widely used in industrial and environmental applications, should be interchangeable and ideally have parametrizable response to relative humidity changes. While the effects of temperatures in the range between 0 °C and 50 °C are negligible, this is not the case for negative values. [...]

Measurement of the charge ratio of atmospheric muons with the CMS detector
/ Kumari, Anita (CSIR NET-JRF)
We present a measurement of the ratio of positive to negative muon fluxes from cosmic ray interactions in the atmosphere, using data collected by the CMS detector both at ground level and in the underground experimental cavern at the CERN LHC. Muons were detected in the momentum range from 5 GeV/c to 1 TeV/c. [...]

Quadrupole and octupole collectivity in the semi-magic nucleus 80206Hg126
/ Morrison, L (Surrey U.) ; Hadyńska-Klȩk, K (Warsaw U., Heavy Ion Lab ; Surrey U.) ; Podolyák, Zs (Surrey U.) ; Gaffney, L P (Liverpool U. ; CERN) ; Zielińska, M (IRFU, Saclay) ; Brown, B A (Michigan State U., East Lansing (main)) ; Grawe, H (Darmstadt, GSI) ; Stevenson, P D (Surrey U.) ; Berry, T (Surrey U.) ; Boukhari, A (CSNSM, Orsay) et al.
The first low-energy Coulomb-excitation measurement of the radioactive, semi-magic, two proton-hole nucleus 206Hg, was performed at CERN's recently-commissioned HIE-ISOLDE facility. Two γ rays depopulating low-lying states in 206Hg were observed. [...]

Irradiation of Multimode Ge-doped and F-doped Optical Fibers at Cryogenic Temperatures Down to 10 K
/ Toccafondo, Iacopo (CERN) ; Alessi, Antonino (Fraunhofer Inst., Euskirchen) ; Blanc, Jeremy (CERN) ; Di Francesca, Diego (CERN) ; Kuhnhenn, Jochen (Fraunhofer Inst., Euskirchen) ; Ricci, Daniel (CERN) ; Weinand, Udo (Fraunhofer Inst., Euskirchen)
The combined effect of radiation and cryogenic temperatures on the response of two different multimode fibers (MMF), one conventional and one radiation resistant, has been investigated. This article presents the outcome of the measurements of the radiation induced attenuation (RIA) in those fibers at 830 nm and 1310 nm under gamma irradiation and at temperatures of 300 K, 218 K, 143 K and 10.

Spectroscopic quadrupole moments in Xe124

Background: The Xe isotopic chain with four valence protons above the Z=50 shell closure is an ideal laboratory for the study of the evolution of nuclear deformation. At the N=82 shell closure, Xe136 presents all characteristics of a doubly closed shell nucleus with a spherical shape. [...]
