Trapping penguins with entangled B mesons

Physics Letters B, 2016
The first direct observation of time-reversal (T) violation in the $B\bar{B}$ system has been reported by the BaBar collaboration, employing the method of Ba$\tilde {\rm n}\!$uls and Bernabéu. Given this, we generalize their analysis of the time-dependent T-violating asymmetry ($A_{T}$) to consider different choices of CP tags for which the dominant ...

Leaf litter and fine roots have distinct effects on particulate and mineral‐associated soil organic matter in a tree common garden

New Phytologist, EarlyView.
Summary Soil organic matter (SOM) is primarily derived from leaf and root inputs, but the relative contributions of each are difficult to study without the use of isotopic tracers. Furthermore, associations between trees and mycorrhizal fungi can influence the production and persistence of SOM.

Cabibbo–Kobayashi–Maskawa-favored B decays to a scalar meson and a D meson

European Physical Journal C: Particles and Fields, 2017
In this work, we attempt to study the Cabibbo–Kobayashi–Maskawa-favored $$B \rightarrow \overline{D} S$$ B → D ¯ S (“S” denoting the scalar meson) decays within the perturbative QCD approach at the leading order and the leading power.

Gall responses to drying habitats: Insights from the community of galling herbivores associated with the superhost Caryocar brasiliense Cambess. (Caryocaraceae)

Plant Biology, EarlyView.
Drying processes in the Brazilian palm swamps or Veredas, impact the gall community in adjacent vegetation by reducing the abundance of more sensitive galls, while more resilient galls acclimate to increased dryness by developing thicker protective tissues. Abstract Galls are new plant organs formed in response to the stimuli of gall‐inducing organisms,

B-meson-quark coupling constant and decay width of B*-meson

Fizika B : a journal of experimental and theoretical physics, 1998
Određuju se konstante vezanja pion – kvark (gπqq) i B-mezon – kvark (gB−qq) u procesima B∗−→B−π0 i B∗−→B−γ. Njihove se širine raspada računaju preko izravnog vezanja π0 i B− s kvarkovima koji miruju u B∗− mezonu.

Study of B Meson Production in p+Pb Collisions at √[S(NN)]=5.02 TeV Using Exclusive Hadronic Decays.

Physical Review Letters, 2015
The production cross sections of the B^{+}, B^{0}, and B_{s}^{0} mesons, and of their charge conjugates, are measured via exclusive hadronic decays in p+Pb collisions at the center-of-mass energy sqrt[s_{NN}]=5.02 TeV with the CMS detector at the CERN ...

Positive mixture effects in pine–oak forests during drought are context‐dependent

Plant Biology, EarlyView.
Mixture effects in drought‐stressed pine‐oak forests are context‐dependent, with Gambel oak and ponderosa pine benefiting from their complementarity under semi‐arid conditions. Abstract The increasing severity and frequency of droughts will play a pivotal role in shaping future forest ecosystems worldwide.

Physics and recent results from LHCb

EPJ Web of Conferences, 2012
The LHCb experiment has collected more than 1 fb-1 of integrated luminosity in 2010 and 2011 and is producing a large amount of results in beauty and charmed meson physics.

Herbaceous plant communities respond more to seasonal precipitation than cumulative drought in the hot deserts of the United States

Plant Biology, EarlyView.
Using a 4‐year drought experiment in the hot deserts of the US, we found that herbaceous plant communities were more sensitive to seasonal precipitation than to the cumulative effects of drought. Abstract The hot deserts of the southwestern United States are experiencing increased frequency, severity, and duration of drought due to anthropogenic ...
