On the integrability of the sine-Gordon system
No full textThis thesis investigates the integrability of the sine-Gordon system of nonlinear partial differential equations when the dependent variables are subject to some very particular boundary conditions. In chapter 1 the sine-Gordon system is introduced and, with N ϵ Z, P, Q ϵ R, the sets of initial-boundary value problems A(_N) and B(_P,Q) are defined. In the set A(_N) at the spatial variable x is unbounded and the boundary conditions are fixed by initially choosing the topological charge N. This set of problems is the one usually associated with the sine-Gordon system. In the set B(_P,Q) the spatial coordinate is constrained to the semi-line (-oo,0) and there exists two boundary parameters P,Q ϵ R to be chosen a priori. It is the study of this second set of initial-boundary value problems for arbitrary P, Q which forms all the original work of this dissertation. The study presented here is primarily concerned with the development of three separate inverse scattering methods for solving these sets of initial-boundary value problems. The first of these is developed in chapter 3 and is applicable to a subset of the problems in A(_N). The method is the one usually associated with the sine-Gordon system and studies the asymptotics of the initial data as x → ±oo. It is included in this thesis for completeness and as background for the original material which follows. Next, in chapters 4 and 5, the inverse scattering methods appropriate to initial-boundary value problems in subsets of B(_P,O) and B(_P,Q#O) are constructed. In these cases it is important to realise that it is only possible to study the asymptotics of the initial data as x → -oo. Once these three methods have been formulated they are used to find soliton solutions and infinite sets of integrals of motion for these boundary value problems. When a boundary is present at x = 0 the interaction of the solitons with this boundary is studied. These topics are addressed in chapter 6. Finally in chapter 7 the question of the integrability of both sets of problems is addressed. By interpreting the various inverse scattering methods in terms of canonical coordinate transformations of phase space it is seen that the existence of such methods can be viewed as a constructive proof of the integrability of these boundary value problems

Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations

Differences appeared trivial, including “the autozooidal sinus, which is more U-shaped, and the pore-chambers which are more triangular” in the New Zealand form. Gordon (1984) described the latter as a new subspecies, <i>H. divaricata pacifica</i>, further noting more-elongate zooeciules, fewer pore-chambers and a kenozooidal ancestrula, but was not able to illustrate the ovicell in the type specimens, noting, however (in remarks on <i>Hippothoa calciophilia</i> Gordon, 1984, p. 110), that the apex of the ovicell in <i>H. divaricata pacifica</i> was bimucronate.</p> <p> The new material gives information on the ovicell, of which the ooecium is indeed bimucronate (Fig. 10A), appearing as a pair of converging, rimmed, drop-shaped tubular (elevated) pseudopores in non-eroded specimens. De Blauwe (2009) has illustrated by SEM Belgian material of <i>H. divaricata</i> —the sole ovicell shown has an ooecium with more-widely separated elevations, each with a small excavation in it. The specimen additionally shows that the autozooids are proportionally narrower and more-strongly carinate than in the New Zealand form, which is here raised to full species rank. Moyano’s (1986) illustrations of <i>H. divaricata</i> from Chile resemble <i>H. pacifica</i> but the ancestrula has an orifice and operculum.</p> <p> <i>Hippothoa pacifica</i> ranges throughout New Zealand from the vicinity of Raoul Island to southern South Island (c. 29– 47° S), where it seems to be restricted to calcareous substrata. It occurs from shallow coastal water to 826 m depth.</p>Published as part of <i>Gordon, Dennis P., 2020, New Hippothoidae (Bryozoa) from Australasia, pp. 451-476 in Zootaxa 4750 (4)</i> on pages 468-469, DOI: 10.11646/zootaxa.4750.4.1, <a href="http://zenodo.org/record/3708766">http://zenodo.org/record/3708766</a>
