B → <i>πlν</i> and B<i>s</i> → K<i>lν</i> decays in the continuum limit of lattice QCD
No full textThe Standard Model of particle physics is our current best model of the fundamental mechanics of nature. However, it cannot explain all observed phenomena, and clearly there must be new physics to uncover. At some level of precision, new physics effects must enter standard model predictions, and present themselves as discrepancies between observation and theory. Finding such clues at the precision frontier will provide valuable input on the advancement of our theoretical understanding of nature. We see intriguing tensions between theoretical expectations and collider experiments for semileptonic heavy-light decays. The expected unitarity of the Cabbibo-Kobayashi-Maskawa (CKM) matrix is in tension with a combination of theoretical calculations and experimental evidence at a 3σ level for the first row of the matrix, and a similar 2 − 3σ discrepancy is present between determinations of the |Vub| matrix element from exclusive B → πlν decays and inclusive B → Xulν decays. Investigating CKM matrix elements such as |Vub| requires the theoretical calculation of QCD form factors, which must be calculated non-perturbatively in the low energy regime of QCD, in combination with observations of decay rates from the B-factories and LHCb. Here we present our work on determining the standard model QCD form factors for B → πlν and Bs → Klν using the non-perturbative lattice QCD technique. Our calculations of these quantities are more precise than a previous 2015 determination currently used in theoretical averages, and by updating these results we anticipate a corresponding increase in precision in these averages. In addition, we investigate a modification to standard lepton flavour universality ratios, which we demonstrate to provide more precise predictions. We suggest that these ratios may be used as an additional way to monitor lepton flavour universality

Data for Thesis " and decays in the Continuum Limit of Lattice QCD"
No full textDataset to support Southampton Doctoral Thesis " and decays in the Continuum Limit of Lattice QCD"
The data files are all in the HDF5 format. These can be viewed using the standard HDF5 command-line tools such as h5dump, or opened with reader libraries such as the h5py Python library.
There are three important datasets in each HDF5 file under the root group:
- central: The timeslice-by-timeslice mean of the raw data.
- bs_mean: The timeslice-by-timeslice mean of the Bootstrap samples.
- samples: The Bootstrap samples in a (Configurations X Timeslices)-shaped matrix.
This dataset contains, for the two processes BtoPi and BstoK:
- data/
The full set of 2pt and 3pt correlators used to extract form factors across square lattice momenta n^2=0,1,2,3,4 and across the six ensembles C1, C2, M1, M2, M3, and F1S.
- B/Bs naming convention: [B/Bs]-[ensemble]-[momentum]-[num_smeared].h5 (where num_smeared=0 -> PointPoint, =1 -> PointSmear, =2 -> SmearSmear)
- K/Pi naming convention: [Pi/K]-[ensemble]-[momentum].h5
- 3pt naming convention: [B/Bs]to[Pi/K]_3pt_[t/i]-[ensemble]-[momentum]
- box/
The additional correlators required for the RHQ parameter "box" systematic analysis on the C1 and M2 ensembles. Final-state correlators are duplicates of the ones in the 'data/' directory.
- B/Bs naming convention: [B/Bs]-[ensemble]-[m_b]-[csw]-[zeta]-[momentum]-[num_smeared].h5 (where num_smeared=0 -> PointPoint, =1 -> PointSmear, =2 -> SmearSmear)

The additional correlators required for the strange-quark mistuning systematic analysis on the C1 ensemble.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
