Present and Future K and B Meson Mixing Constraints on TeV Scale Left-Right Symmetry [PDF]
, 2014 We revisit the Δ F = 2 transitions in the K and B d , s neutral meson systems in the context of the minimal left-right symmetric model. We take into account, in addition to up-to-date phenomenological data, the contributions related to the ...

Lessons from an eradication under multiple constraints of an island rat population of record density
Conservation Biology, EarlyView.Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

Logarithmic moments of B-meson quasidistribution amplitude
European Physical Journal C: Particles and FieldsIt was demonstrated that the lattice simulation of B-meson light-cone distribution amplitude (LCDA) is feasible via the quasi-distribution amplitude (quasi-DA) in large momentum effective theory (LaMET).

B-meson decay constants from 2+1-flavor lattice QCD with domain-wall light quarks and relativistic heavy quarks [PDF]
, 2014 We calculate the B-meson decay constants fB, fBs, and their ratio in unquenched lattice QCD using domain-wall light quarks and relativistic b-quarks. We use gauge-field ensembles generated by the RBC and UKQCD collaborations using the domain-wall fermion

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

CP Violation in B Meson Decays [PDF]
Nuclear Physics B - Proceedings Supplements, 2005 Recent CP asymmetry measurements in tree-dominated processes, $B^0\to ^+ ^-, ^+ ^-, ^{\pm} ^{\mp}, B^+\to DK^+$, and in penguin-dominated decays, $B \to ^0 K_S, ' K_S, K_S$, are interpreted in the framework of the Kobayashi-Maskawa (KM) mechanism of CP violation.

Ecography, EarlyView.Litter decomposition in mountainous forest ecosystems is an essential process that affects carbon and nutrient cycling. However, the contribution of litter decomposition to terrestrial ecosystems is difficult to estimate accurately because of the limited comparability of different studies and limited data on local microclimatic and non‐climatic factors.

The decays B→Ψ(2S)π(K),ηc(2S)π(K) in the pQCD approach beyond the leading-order
Physics Letters B, 2017 Two body B meson decays involving the radially excited meson ψ(2S)/ηc(2S) in the final states are studied by using the perturbative QCD (pQCD) approach. We find that: (a) The branching ratios for the decays involving a K meson are predicted as Br(B+→ψ(2S)
