D*(s0)(2317) meson and D-meson-kaon scattering from lattice QCD. [PDF]

Physical Review Letters, 2013
The scalar meson D*(s0)(2317) is found 37(17) MeV below the DK threshold in a lattice simulation of the J(P)=0(+) channel using, for the first time, both DK as well as s¯c interpolating fields. The simulation is done on N(f)=2+1 gauge configurations with

Medium induced Lorentz symmetry breaking effects in nonlocal PNJL models [PDF]

, 2014
In this paper we detail the thermodynamics of two flavor nonlocal Polyakov-Nambu-Jona-Lasinio models for different parametrizations of the quark interaction regulators.

Trade‐offs among restored ecosystem functions are context‐dependent in Mediterranean‐type regions

Ecography, EarlyView.
Global biodiversity hotspots, including Mediterranean‐type ecosystems worldwide, are highly threatened by global change that alters biodiversity, ecosystem functions, and services. Some restoration activities enhance ecosystem functions by reintroducing plant species based on known relationships between plant traits and ecosystem processes.

Meson turbulence at quark deconfinement from AdS/CFT

Nuclear Physics B, 2015
Based on the QCD string picture at confining phase, we conjecture that the deconfinement transition always accompanies a condensation of higher meson resonances with a power-law behavior, “meson turbulence”.

Neutral $B$ meson mixings and $B$ meson decay constants with static heavy and domain-wall light quarks [PDF]

, 2014
Neutral $B$ meson mixing matrix elements and $B$ meson decay constants are calculated. Static approximation is used for $b$ quark and domain-wall fermion formalism is employed for light quarks.

B-Meson Wavefunction in the Wandzura-Wilczek Approximation

, 2005
The B-meson wavefunction has been studied with the help of the vacuum-to-meson matrix element of the nonlocal operators in the heavy quark effective theory.

Selection of meadow fescue for persistence under frequent defoliation

Grassland Research, EarlyView.
Meadow fescue was adapted to management intensive grazing in humid temperate regions. It does not tolerate highly intensive grazing with short rest periods or residual sward heights below 5 cm. This paper documents genetic progress in selecting for improved tolerance to frequent and close grazing.

Spectrum of mesons and hyperfine dependence potentials

Iranian Journal of Physics Research, 2006
In most models, mesons consist of quark -antiquark pairs moving in a confining potential. However, it would be interesting to consider the effect of an extra residual interaction by introducing the quark particles which contain a dependent spin and ...

Meson scattering in a non-minimally Lorentz-violating scalar QED at finite temperature

European Physical Journal C: Particles and Fields
In this paper we study meson scattering in a non-minimally Lorentz-violating scalar QED at finite temperature. The meson scatterings were investigated in tree level and the finite temperature effects were addressed by using the thermofield dynamics ...

The UTfit collaboration average of D meson mixing data: Winter 2014 [PDF]

, 2014
A bstractWe update the analysis of D meson mixing including the latest experimental results as of January 2014. We derive constraints on the parameters M12, Γ12 and Φ12 that describe D meson mixing using all available data, allowing for CP violation.
