Investigation into theB(E2)anomaly inNd144…

Physical Review C (2008)

C. Fitzpatrick V. Werner R. F. Casten E. Williams H. Ai

The ratio of $B(E2)$ strengths between the lowest lying members of the ground state band in $^{144}\mathrm{Nd}$, ${B}_{4/2}=B(E2;{4}_{1}^{+}\ensuremath{\rightarrow}{2}_{1}^{+})/B(E2;{2}_{1}^{+}\ensuremath{\rightarrow}{0}_{1}^{+})$, which is used to quantify collectivity in nonmagic nuclei, has been remeasured by means of Coulomb excitation. Ambiguities in literature values for this ratio have been resolved. The results are discussed in terms of the interplay of collective and single-particle degrees of freedom, and in the context of the formation of collective structures in the $A=140$ mass region, and more generally near (sub)shell closures. In addition, the ${B}_{4/2}$ ratio of $^{148}\mathrm{Sm}$ has been remeasured, and the quadrupole moment of the ${4}_{1}^{+}$ state is found to be on the order of $1 e b$.

Measurement of the effective leptonic weak mixing angle

Journal of High Energy Physics (2024)

R. Aaij A. S. W. Abdelmotteleb C. Abellán Beteta F. Abudinén T. Ackernley

A bstract Using pp collision data at $$ \sqrt{s} $$ s = 13 TeV, recorded by the LHCb experiment between 2016 and 2018 and corresponding to an integrated luminosity of 5 . 4 fb − 1 , the forward-backward asymmetry in the pp → Z/γ * → μ + μ − process is measured. The measurement is carried out in ten intervals of the difference between the muon pseudorapidities, within a fiducial region covering dimuon masses between 66 and 116 GeV, muon pseudorapidities between 2 . 0 and 4 . 5 and muon transverse momenta above 20 GeV. These forward-backward asymmetries are compared with predictions, at next-to-leading order in the strong and electroweak couplings. The measured effective leptonic weak mixing angle is $$ {\sin}^2{\theta}_{\textrm{eff}}^{\ell }=0.23147\pm 0.00044\pm 0.00005\pm 0.00023, $$ sin 2 θ eff ℓ = 0.23147 ± 0.00044 ± 0.00005 ± 0.00023 , where the first uncertainty is statistical, the second arises from systematic uncertainties associated with the asymmetry measurement, and the third arises from uncertainties in the fit model used to extract $$ {\sin}^2{\theta}_{\textrm{eff}}^{\ell } $$ sin 2 θ eff ℓ from the asymmetry measurement. This result is based on an arithmetic average of results using the CT18, MSHT20, and NNPDF31 parameterisations of the proton internal structure, and is consistent with previous measurements and with predictions from the global electroweak fit.

Robustness to misalignment of low-cost, compact quantitative phase imaging architectures

OSA Continuum (2020)

C. Fitzpatrick Abby Wilson Travis W. Sawyer Peter J. Christopher Timothy D. Wilkinson

Non-interferometric approaches to quantitative phase imaging could enable its application in low-cost, miniaturised settings such as capsule endoscopy. We present two possible architectures and both analyse and mitigate the effect of sensor misalignment on phase imaging performance. This is a crucial step towards determining the feasibility of implementing phase imaging in a capsule device. First, we investigate a design based on a folded 4f correlator, both in simulation and experimentally. We demonstrate a novel technique for identifying and compensating for axial misalignment and explore the limits of the approach. Next, we explore the implications of axial and transverse misalignment, and of manufacturing variations on the performance of a phase plate-based architecture, identifying a clear trade-off between phase plate resolution and algorithm convergence time. We conclude that while the phase plate architecture is more robust to misalignment, both architectures merit further development with the goal of realising a low-cost, compact system for applying phase imaging in capsule endoscopy.

Quantitative phase and polarization imaging through an optical fiber applied to detection of early esophageal tumorigenesis

Journal of Biomedical Optics (2019)

George S. D. Gordon James Joseph Maria P. Alcolea Travis W. Sawyer Calum Williams

Phase and polarization of coherent light are highly perturbed by interaction with microstructural changes in premalignant tissue, holding promise for label-free detection of early tumors in endoscopically accessible tissues such as the gastrointestinal tract. Flexible optical multicore fiber (MCF) bundles used in conventional diagnostic endoscopy and endomicroscopy scramble phase and polarization, restricting clinicians instead to low-contrast amplitude-only imaging. We apply a transmission matrix characterization approach to produce full-field en-face images of amplitude, quantitative phase, and resolved polarimetric properties through an MCF. We first demonstrate imaging and quantification of biologically relevant amounts of optical scattering and birefringence in tissue-mimicking phantoms. We present an entropy metric that enables imaging of phase heterogeneity, indicative of disordered tissue microstructure associated with early tumors. Finally, we demonstrate that the spatial distribution of phase and polarization information enables label-free visualization of early tumors in esophageal mouse tissues, which are not identifiable using conventional amplitude-only information.
