Lepton flavor non-universality in B-meson decays from a U(2) flavor model [PDF]
Journal of High Energy Physics, 2015 We address the recent anomalies in semi-leptonic B-meson decays using a model of fermion masses based on the U(2) flavor symmetry. The new contributions to b → sℓℓ transitions arise due to a tree-level exchange of a Z′ vector boson gauging a U(1 ...

Grassland Research, EarlyView.Cattle grazing meadow fescue pasture in remnant oak savanna near Fennimore, Wisconsin. Abstract Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is highly adapted to managed rotational grazing systems with sufficient rest periods to promote regrowth and sward longevity.

Optimizing Soil Properties Through Hydrogel and Sawdust Combinations for Better Plant Growth
Journal of Plant Nutrition and Soil Science, EarlyView.This graphical abstract illustrates the effects of various soil amendments on poplar cutting vitality under drought conditions, as observed using X‐ray computed tomography (CT). It compares soil alone, soil with sawdust, soil with hydrogel, and their combination, highlighting differences in internal structure, water retention, and root development.

Lepton universality violation with lepton flavor conservation in B-meson decays [PDF]
, 2015 A bstractAnomalies in semileptonic B-meson decays present interesting patterns that might be revealing the shape of the new physics to come. Under the assumption that neutrino and charged lepton mass terms are the only sources of flavor violation and ...

Nordic Journal of Botany, EarlyView.Understanding community assembly for wild species in anthropogenic settings has become increasingly important as biodiversity and ecosystem services are threatened by development pressures. Urban hardscape habitats such as parking lots are widespread, extreme, terrestrial anthropogenic environments that influence plant community assembly by way of ...

Renormalization group analysis of B → π form factors with B -meson light-cone sum rules [PDF]
, 2016 Within the framework of the $B$-meson light-cone sum rules, we review the calculation of radiative corrections to the three $B\ensuremath{\rightarrow}\ensuremath{\pi}$ transition form factors at leading power in $\mathrm{\ensuremath{\Lambda}}/{m}_{b ...

Micromorpho‐anatomical studies on the leaves and woods of Turkish Daphne (Thymelaeaceae) taxa
Nordic Journal of Botany, EarlyView.The identification of Daphne taxa is difficult because of the lack of available morphological characteristics. Here, we aimed to describe leaf and wood micromorpho‐anatomical characteristics of native Turkish Daphne taxa (D. glomerata, D. gnidioides, D. mezereum, D. mucronata, D. oleoides subsp. kurdica, D. pontica and D.

Probing the inverse moment of B s -meson distribution amplitude via B s → η s form factors
Journal of High Energy PhysicsWe investigate the inverse moment of the B s -meson light-cone distribution amplitude (LCDA), denoted as λ B s $$ {\lambda}_{B_s} $$ and defined within the heavy quark effective theory, through the calculation of B s → η s form factors.

Scrutinizing Dark-Matter Scenarios with B → (K,
UniverseConceivable explanations of Belle-II measurements of a (surprising) excess of missing energy decays of the B meson to the K meson not covered by standard model neutrino–antineutrino pairs might be offered by additional contributions of dark matter ...

Mass of the b quark and B -meson decay constants from Nf=2+1+1 twisted-mass lattice QCD [PDF]
, 2016 We present precise lattice computations for the b-quark mass, the quark mass ratios m(b)/m(c) and m(b)/m(s) as well as the leptonic B-decay constants. We employ gauge configurations with four dynamical quark flavors, up-down, strange and charm, at three ...
