Effects of long-term preservation on amphibian body conditions: implications for historical morphological research [PDF]

PeerJ, 2017
Measurements of historical specimens are widely applied in studies of taxonomy, systematics, and ecology, but biologists often assume that the effects of preservative chemicals on the morphology of amphibian specimens are minimal in their analyses.

Quark mass effects in two-loop Higgs amplitudes

Journal of High Energy Physics, 2020
We provide two two-loop amplitudes relevant for precision Higgs physics. The first is the two-loop amplitude for Higgs boson production through gluon fusion with exact dependence on the top quark mass up to squared order in the dimensional regulator ε ...

Target Mass Effects in Polarized Virtual Photon Structure Functions [PDF]

, 2003
We study target mass effects in the polarized virtual photon structure functions $g_1^\gamma (x,Q^2,P^2)$, $g_2^\gamma (x,Q^2,P^2)$ in the kinematic region $\Lambda^2\ll P^2 \ll Q^2$, where $-Q^2 (-P^2)$ is the mass squared of the probe (target) photon ...

Light Quark Mass Effects in Bottom Quark Mass Determinations [PDF]

, 2001
Recent results for charm quark mass effects in perturbative bottom quark mass determinations from $\Upsilon$ mesons are reviewed. The connection between the behavior of light quark mass corrections and the infrared sensitivity of some bottom quark mass ...

Quark mass effects in B -> Xs gamma

, 2001
The charm-loop contribution to B -> Xs gamma is found to be numerically dominant and very stable under logarithmic QCD corrections. The strong enhancement of the branching ratio by QCD logarithms is mainly due to the b-quark mass evolution in the top ...

Quark masses in Higgs production with a jet veto [PDF]

, 2014
We study the impact of finite mass effects due to top and bottom loops in the jet-veto distribution for Higgs production. We discuss the appearance of non-factorizing logarithms in the region p t,veto ≳ m b .

Mass-suppressed effects in heavy quark diffusion

Journal of High Energy Physics, 2020
Many lattice studies of heavy quark diffusion originate from a colour-electric correlator, obtained as a leading term after an expansion in the inverse of the heavy-quark mass.

Effects of ovule and seed abortion on brood size and fruit costs in the leguminous shrub Caesalpinia gilliesii (Wall. ex Hook.) D. Dietr

Acta Botânica Brasílica, 2014
For several plant species, brood size results from the abortion of ovules and seeds. However, these processes have rarely been studied together in wild plants.

Semi-perturbative unification with extra vector-like families [PDF]

, 1999
We make a comprehensive analysis of an extended supersymmetric model(ESSM) obtained by adding a pair of vector-like families to the minimal supersymmetric standard model and having specific forms of 5 x 5 fermion mass matrices.
