We report a measurement of time-dependent CP violation parameters in B 0 → K 0 S ηγ decays. The study is based on a data sample, containing 772 × 10 6 BB pairs, that was collected at the ϒð4SÞ resonance with the Belle detector at the KEKB asymmetric-energy e þ e − collider. We obtain the CP violation parameters of S ¼ −1.32 AE 0.77ðstatÞ AE 0.36ðsystÞ and A ¼ −0.48 AE 0.41ðstatÞ AE 0.07ðsystÞ for the invariant mass of the K 0 S η system up to 2.1 GeV=c 2 .

“…In order to determine S f it is necessary to determine the flavour of the B meson at production using flavour tagging techniques. This time-dependent technique has been exploited by the BaBar and Belle experiments to determine S K * γ (using K * → K 0 π 0 ) [144,145], S K S ηγ [146] and S K S ρ 0 γ [147,148].

One of the most interesting puzzles in particle physics today is that new physics is expected at the TeV energy scale to solve the hierarchy problem, and stabilise the Higgs mass, but so far no unambiguous signal of new physics has been found. Strong constraints on the energy scale of new physics can be derived from precision tests of the electroweak theory and from flavour-changing or CP -violating processes in strange, charm and beauty hadron decays. Decays that proceed via flavour-changing-neutral-current processes are forbidden at the lowest perturbative order in the Standard Model and are, therefore, rare. Rare b hadron decays are playing a central role in the understanding of the underlying patterns of Standard Model physics and in setting up new directions in model building for new physics contributions. In this article the status and prospects of this field are reviewed.

“…momentum) in the Hilbert space. The RR series are explicit examples where part of the translationally invariant Hilbert space in a single LL is truncated, as manifested by their entanglement spectrum [23]. The integer quantum Hall effect also fits in this paradigm: while the permissible Hilbert space includes all Landau levels and realistic ground states have small components in higher LLs, the minimal model ground state is the Vandermonde of the lowest filled LLs with all higher LLs truncated.…”

“…To better understand the differences between the two states at ν = 3/7 obtained from qualitatively different LECs, we use topological entanglement spectrum (ES) [23] to analyse these many-body states. One should note that our model states are explicitly constructed from a truncated Hilbert space within a single LL, thus only the topological part of ES will be present.…”

Emergent commensurability from Hilbert space truncation in fractional quantum Hall fluids

We show that model states of fractional quantum Hall fluids at all experimentally detected plateaus can be uniquely determined by imposing translational invariance with a particular scheme of Hilbert space truncation. The truncation is based on classical local exclusion conditions, motivated by constraints on physical measurements. The scheme allows us to identify filling factors, topological shifts and clustering of topological quantum fluids universally without resorting to microscopic Hamiltonians. This prompts us to propose the notion of emergent commensurability as a fundamental property for many known FQH states, which allows us to predict families of new FQH state that can be realised in principle. We also discuss the implications of certain missing states proposed from other phenomenological approaches, and suggest that the physics of FQH effect could fundamentally arise from the algebraic structure of the Hilbert space in a single Landau level.A large number of fractional quantum Hall (FQH) states with distinct topological orders have been observed experimentally and proposed theoretically, ever since the surprising discovery of the quantised Hall conductivity at 1/3 filling factor [1, 2]. The physics of the FQH effect is mainly derived from the formation of an incompressible quantum fluid with a charge excitation gap, which could be realised at specific rational filling factors when a two-dimensional electron gas system is subject to a perpendicular magnetic field. We now understand that both Abelian and non-Abelian FQH states are likely observed in the experiments [1, 3]. In addition to the single component FQH states (e.g. the Read-Rezayi series [4,5]), there can also be multi-component or hierarchical states from the coexistence of more than one type of quantum fluids in a strongly correlated manner [6,7].There has been much development in the microscopic theories of the FQH effect since the first proposition of the Laughlin wavefunctions[2] and later on, the model Hamiltonians [8]. One major approach is the phenomenological formation of "composite fermions" (CF) with flux attachment [7], and the parton construction inspired from it [9,10]. It leads to the systematic construction of microscopic wavefunctions for almost all observed and proposed FQH states [11]. Another major approach is to exploit the rich algebraic structures of many-body wavefunctions in a single Landau level (LL) on genus 0 geometries (e.g. sphere or disk), leading to very efficient constructions of microscopic model wavefunctions with the Jack polynomial formalism [1,12,14,15]. The method is particularly useful for the Read-Rezayi (RR) series including the coveted non-Abelian states, revealing the particle clustering properties in an intuitive manner. The Jack polynomial formalism and the related techniques are also closely linked to the wavefunction constructions from parafermion correlators in conformal field theory (CFT) [4,5], and in contrast to the CF approach, in many cases model projection Hamiltonians can be found [16], o...
