D* and B* mesons in strange hadronic medium at finite temperature

open access: yesEPJ Web of Conferences, 2016
We calculate the effect of density and temperature of isospin symmetric strange medium on the shift in masses and decay constants of vector D and B mesons using chiral SU(3) model and QCD sum rule approach.

B decays into light mesons [PDF]

open access: yes, 1998
I calculate the form factors describing semileptonic and penguin induced decays of B mesons into light pseudoscalar and vector mesons. The form factors are calculated from QCD sum rules on the light-cone including contributions up to twist 4, radiative ...

A Review of Hadronic and Rare B Decays

open access: yes, 1994
We review recent experimental results on B meson decays. These include measurements of the inclusive production of charmed and non-charmed mesons and baryons, the reconstruction of a large number of exclusive hadronic final states with charmed mesons ...

Using dendroclimatic analysis of exotic deciduous conifers in an arboretum to document tree growth in response to climate change, Northeast Ohio, USA

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Rising temperatures and wetter conditions in the Midcontinent of North America are influencing climate responses in trees. Dendroclimatological analyses of four exotic deciduous conifer species from Secrest Arboretum, Northeast Ohio help identify past, present and future climate‐tree interactions.

Decay Constants of Heavy Vector Mesons in Relativistic Bethe-Salpeter Method

open access: yes, 2005
In a previous letter, we computed the decay constants of heavy pseudoscalar mesons in the framework of relativistic (instantaneous) Bethe-Salpeter method (full $0^-$ Salpeter equation), in this letter, we solve the full $1^-$ Salpeter equation and ...

Diverse Prairie Mixtures Stabilize Biomass Yields for Sustainable Aviation Fuel Production

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Meeting global demand for sustainable aviation fuel will require the additional production of vast quantities of plant biomass, which does not compete with food production or degrade sensitive ecosystems. Our multisite experiment shows that sowing diverse native prairie seed mixes—and managing them without intensive inputs—yields a more reliable ...

Perspectives and behaviors surrounding planting practices in North America inform genetic conservation realities for American ginseng (Panax quinquefolius)

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
American ginseng is a shade‐obligate, North American medicinal plant that is widely traded and used internationally. To meet global demand, ginseng is cultivated in forest farms in the Appalachian region of the USA and field‐based artificial shade farms in two regions: Ontario, Canada and Wisconsin, USA. We conducted social research leveraging in‐depth

Colonisation potential of the bark beetle (Taphrorychus bicolor) on beech logs and logging residues: ecological context and implications for pest management in forests

open access: yesPest Management Science, EarlyView.
Beech residues left in shaded or semi‐shaded conditions pose a substantial risk of local Taphrorychus bicolor population outbreaks. The rapid removal or placement of residues in sun‐exposed locations can help mitigate this risk. Abstract BACKGROUND The bark beetle Taphrorychus bicolor has been traditionally classified as a secondary pest of European ...

Semileptonic B and $$B_s$$ Bs decays involving scalar and axial-vector mesons

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We report our theoretical calculations on the branching fractions for the semileptonic B and $$B_s$$ Bs decays based on the form factors in the covariant light-front quark model. That is, $$B (B_s) \rightarrow (P,\, V,\, S,\,A) \ell \nu _\ell $$ B(Bs)→(P,

Precise Measurement of B Meson Lifetimes with Hadronic Decay Final States

open access: yes, 2002
The lifetimes of the B0bar and B- mesons are extracted from 29.1/fb of data collected with the Belle detector at the KEK B-factory. A fit to the decay length differences of neutral and charged B meson pairs, measured in events where one of the B mesons ...
