Spin parity studies of the eta pi decay of the A2 meson and investigation of the A2 production mechanism in the reaction pi-minus proton goes to A2-minus proton
The results of a spin parity analysis of the nv-decay mode of the A-meson produced in the reaction A2-p -A2-pare presented. Data for the analysis are drawn from bubble chamber experiments between 3.9 and 16 GeV/c. The analysis favors JP=Z+ for both the upper and lower regions of the AZ' Possible …

Observation of eta-c and other structures in the radiative decay psi to gamma eta pi-plus pi-minus
… to observe the exclusive radiative decay [...] A spin-parity analysis was performed to determine the quantum numbers of the resonances responsible for this structure. However, the result was seen to be model dependent, so that it was not possible to conclusively resolve the underlying structure in …

Three pion production on complex nuclei at 23 GeV/c
… the method of their computation is outlined. The spin-parity composition of the three-pion system has been analyzed using the Illinois method of partial wave analysis. The partial wave structure of the data is remarkably similar to that of the data from hydrogen, excepting the distributions in …

Measurement of Higgs couplings to top quarks and τ leptons with the ATLAS detector
… to characterize its properties. Its mass, spin, parity and couplings have been studied in detail with no significant deviations from the SM predictions observed. The second run of the LHC saw incredible progress with the addition of new measurements. This thesis highlights the measurements …

High-Precision Half-Life Measurement of Oxygen-14
… between nuclear isobaric analogue states of spin-parity Jπ= 0+, T = 1 provide fundamental tests of the electroweak interaction. These transitions are used to constrain the conserved vector current (CVC) hypothesis and provide the most precise value of Vud, the updown element of the …

Production of three charged pions in pi minus proton interactions at 5 Bev/c
… with this enhancement being a state of spinparity I+ with J = 0 along the incident pion direction. It does not z appear to be entirely due to a Deck-type kinematic effect. (3) Three peaks of marginal statistical significance in the pi+pi-pi- mass, with masses (and widths) 1.06 Bev (40 …

A-2 meson production in pi-minus proton interactions at five BeV
… reported at other incident pion momenta. The spin-parity analysis of the Ppi decay mode yields results p + which are consistent with a J = 2 assignment for both halves of the A2"" The angular distribution of the decay plane indicates a J = 2 spin state with alkl = 1 component along the normal …

Skyrmions -- beyond rigid body quantisation
… body quantisation, the Skyrme model predicts a spin $\frac{7}{2}$ ground state while in reality the Lithium-$7$ nucleus ground state has spin $\frac{3}{2}$. We show that a quantisation which includes a $5$-dimensional vibrational manifold of deformed Skyrme configurations remedies this problem, …
