TL;DR: In this paper, the number density of created electron-positron pairs in a frequency modulated laser field is investigated using quantum kinetic equation, and it is found that the momentum spectrum presents an obvious interference pattern.

TL;DR: In this article, a search for decays of Bc + mesons to two charm mesons is performed for the first time using data corresponding to an integrated luminosity of 3.0fb−1, collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and 8 TeV.

TL;DR: Wang et al. as mentioned in this paper constructed a tripartite evolutionary game model of enterprises, governments and financial institutions, and used the evolutionary game theory and MATLAB simulation to analyze the evolutionary process of the interaction of the subjects of the green technology innovation of enterprises under the dual environmental regulation.

TL;DR: The first observation of the decay of a B0 meson to a purely baryonic final state, B0→pp, is reported in this article, where the branching fraction is determined to be B(B 0→pp)=(1.25±0.18)×10-8, where the first uncertainty is statistical and the second systematic.
