ρ meson decays of heavy hybrid mesons
Chinese Physics C, 2016 We calculate the $\rho$ meson couplings between the heavy hybrid doublets H^h/S^h/M^h/T^h and the ordinary q\bar{Q} doublets in the framework of the light-cone QCD sum rule. The sum rules obtained rely mildly on the Borel parameters in their working regions. The resulting coupling constants are rather small in most cases.

Journal of Animal Ecology, EarlyView.This study investigates how large mammalian herbivores shape arthropod communities in African savannas, using a broad gradient of herbivory types and intensities to assess these effects under real‐world, non‐experimental conditions. Abstract Savanna ecosystems support unique biodiversity and provide livelihoods for millions of people.

An Overlooked Habitat‐Dependent Link Between Metabolism and Water Loss in Reptiles
Integrative Zoology, EarlyView.We measured the gas exchange of six lizard and six snake species, under high and low air humidity, and two intriguing patterns emerged. First, although desert species lose less water via evaporation than similar‐sized mesic species under similar conditions, water loss is virtually the same when each is exposed to its natural conditions.

Potentials between heavy-light mesons from lattice and inverse scattering theory
, 1997 We extend our investigation of heavy-light meson-meson interactions to a system consisting of a heavy-light meson and the corresponding antiparticle.

Meson spectroscopy and properties using Dyson-Schwinger equations [PDF]
, 2006 We study pseudoscalar and scalar mesons using a practical and symmetry preserving truncation of QCD's Dyson-Schwinger equations. We investigate and compare properties of ground and radially excited meson states.

Meson Spectroscopy in AdS/CFT with Flavour [PDF]
, 2003 We compute the meson spectrum of an = 2 super Yang-Mills theory with fundamental matter from its dual string theory on AdS5 × S5 with a D7-brane probe [1].

Hadronic charmed meson decays involving tensor mesons [PDF]
Physical Review D, 2003 Charmed meson decays into a pseudoscalar meson P and a tensor meson T are studied. The charm to tensor meson transition form factors are evaluated in the Isgur-Scora-Grinstein-Wise (ISGW) quark model. It is shown that the Cabibbo-allowed decay $D_s^+\to f_2(1270) ^+$ is dominated by the W-annihilation contribution and has the largest branching ratio ...

Integrative Zoology, EarlyView.Soil drought imposes moderate, temporary costs on a strictly fossorial amphisbaenian reptile. However, these animals seem to cope with, at least, moderately short droughts thanks to their peculiar adaptations to living in an underground environment. ABSTRACT The physiological traits of animals can be strongly influenced by climatic fluctuations, and ...

Radiative decays of vector and pseudoscalar nonets
EPJ Web of Conferences, 2012 Using a counting scheme which treats the light pseudoscalar and the light vector-meson nonet on equal footing, the decays of the narrow light vector mesons into a pseudoscalar meson and a dilepton and of the η′ meson into an ɷ meson and a dielectron are ...

Distillation of scalar exchange by coherent hypernucleus production in antiproton–nucleus collisions
Physics Letters B, 2017 The total and angular differential cross sections of the coherent process p¯+AZ→ΛA(Z−1)+Λ¯ are evaluated at the beam momenta 1.5÷20 GeV/c within the meson exchange model with bound proton and Λ-hyperon wave functions.
