Semileptonic decays and ∣Vxb∣|V_{xb}| determinations

We briefly summarize up-to-date results on the determination of the parameters of the Cabibbo-Kobayashi-Maskawa matrix $|V_{cb}|$ and $|V_{ub}|$, which play an important role in the unitarity triangle and in testing the Standard Model, and recent results on semileptonic $B$ meson decays involving a $\tau$ lepton.Comment: Plenary talk at 6th International Conference on New Frontiers in Physics (ICNFP 2017), 17-26 Aug 2017, Kolymbari, Crete, Greece. arXiv admin note: text overlap with arXiv:1612.0376

Decay widths of the spin-2 partners of the X(3872)

We consider the X(3872) resonance as a JPC=1++ DD¯∗ hadronic molecule. According to heavy quark spin symmetry, there will exist a partner with quantum numbers 2++, X2, which would be a D∗D¯∗ loosely bound state. The X2 is expected to decay dominantly into DD¯, DD¯∗ and D¯D∗ in d-wave. In this work, we calculate the decay widths of the X2 resonance into the above channels, as well as those of its bottom partner, Xb2, the mass of which comes from assuming heavy flavor symmetry for the contact terms. We find partial widths of the X2 and Xb2 of the order of a few MeV. Finally, we also study the radiative X2→DD¯∗γ and Xb2→B¯B∗γ decays. These decay modes are more sensitive to the long-distance structure of the resonances and to the DD¯∗ or BB¯∗ final state interaction

Global fit to b→cτνb \to c\tau\nu anomalies 2022 mid-autumn

Recently, the LHCb collaboration announced a preliminary result of the test of lepton flavor universality (LFU) in $B\to D^{(\ast)}$ semi-leptonic decays: $R_{D}^{\rm LHCb2022} = 0.441 \pm 0.089$ and $R_{D^{\ast}}^{\rm LHCb2022} = 0.281 \pm 0.030$ based on the LHC Run 1 data. This is the first result of $R_{D}$ for the LHCb experiment, and its precision is comparable to the other $B$-factory data. Interestingly, those data prefer the violation of the LFU again. A new world average of the data from the BaBar, Belle, and LHCb collaborations is $R_{D} = 0.358 \pm 0.027$ and $R_{D^{\ast}} = 0.285 \pm 0.013$. Including this new data, we update a circumstance of the $b \to c \tau \overline\nu$ measurements and their implications for new physics. Incorporating recent developments for the $B \to D^{(\ast)}$ form factors in the Standard Model (SM), we observe a $4.1 \sigma$ deviation from the SM predictions. Our updates also include; model-independent new physics (NP) formulae for the related observables; and the global fittings of parameters for leptoquark scenarios as well as single NP operator scenarios. Furthermore, we show future potential to indirectly distinguish different new physics scenarios with the use of the precise measurements of the polarization observables in $B\to D^{(\ast)}\tau \overline\nu$ at the Belle II and the high-$p_{\rm T}$ flavored-tail searches at the LHC. We also discuss an impact on the LFU violation in $\Upsilon \to l^+ l^-$.Comment: 38 pages, 5 figures, 6 Tables; v2: references adde

Aspectos relevantes de la investigación jurídica en economía social

RÉSUMÉ: Au cours des vingt dernières années, la recherche juridique sur l’économie sociale a connu un développement remarquable. Cet article cherche à mettre en relief certains de ses principaux aspects, en se référant aux principaux axes de recherche suivis et aux tendances d’avenir. Les sujets qui furent l’objet de recherche ont été regroupés en fonction de leur contribution à la délimitation des formes juridiques que recouvre l’économie sociale ; à l’étude des entités d’économie sociale dans le cadre constitutionnel ; à l’interprétation des lois régulant les diverses formes juridiques de l’économie sociale ; à la délimitation des compétences entre l’État et les Communautés autonomes ; à l’étude sur la nature, les objectifs et les caractéristiques essentielles des entités d’économie sociale ; et aux principaux thèmes qui abordent son régime juridique. L’analyse des publications antérieures a conduit à l’ébauche des voies possibles de développement de la recherche analysée. Une référence bibliographique exhaustive a été incluse.ABSTRACT: There has been a considerable growth in legal research on the social economy over the last twenty years. The purpose of this article is to present some of the most important aspects of this work, referring to the key areas of research covered and future trends. We have grouped the subjects being researched according to their contribution towards establishing the legal statuses of businesses in the social economy, work on social economy enterprises within the constitutional framework, commentaries on the laws that regulate the different legal statuses of businesses in the social economy, establishing the responsibilities of the State and Autonomous Regions, studying the nature, purposes and characteristic features of social economy enterprises, and the key issues to be considered with regard to the legal system that governs them. Having analysed works published on such matters, we have outlined some possible ways of further developing the research that has been studied. An extensive bibliography is also included.La investigación jurídica sobre economía social durante los últimos veinte años ha experimentado un notable crecimiento.

Semileptonic BB and BsB_s decays involving scalar and axial-vector mesons

We report our theoretical calculations on the branching fractions for the semileptonic $B$ and $B_s$ decays, i.e., $B (B_s) \to (P,\, V,\, S,\,A) \ell \nu_\ell$, where $P$ and $V$ denote the pseudoscalar and vector mesons, respectively, while $S$ denotes the scalar meson with mass above 1 GeV and $A$ the axial-vector meson. The branching fractions for the semileptonic $B\to P$ and $V$ modes have been measured very well in experiment and our theoretical values are in good agreement with them. The ones for $B\to S$ and $A$ modes are our theoretical predictions. There is little experimental information on the semileptonic $B_s$ decays although much theoretical effort has been done. In addition, we predict the branching fractions of $B\to D^*_0(2400) \ell \bar\nu_\ell$ and $B_s\to D^{*-}_{s0}(2317) \ell \bar\nu_\ell$ as $(2.31\pm 0.25)\times 10^{-3}$ and $(3.07\pm0.34)\times 10^{-3}$, in order, assuming them as the conventional mesons with quark-antiquark configuration. The high luminosity $e^+e^-$ collider SuperKEKB/Belle-II is running, with the data sample enhanced by a factor of 40 compared to Belle, which will provide huge opportunity for the test of the theoretical predictions and further help understand the inner structure of these scalar and axial vector mesons, e.g., the glueball content of $f_0(1710)$ and the mixing angles for the axial-vector mesons. These decay channels can also be accessed by the LHCb experiment.Comment: final version, will appear in EPJC, one more reference adde
