The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; show every role.

We present allowed regions in the space of observables of certain non-leptonic B-meson decays that characterize these modes within the Standard Model. A future measurement of observables lying significantly outside of these regions would indicate the presence of new physics. Making use of SU(3) arguments, we give the range for $B\to\pi K$ decays, and for the system of $B_d\to\pi^+\pi^-$, $B_s\to K^+K^-$ modes.

The paper

Original abstract

We present allowed regions in the space of observables of certain non-leptonic B-meson decays that characterize these modes within the Standard Model. A future measurement of observables lying significantly outside of these regions would indicate the presence of new physics. Making use of SU(3) arguments, we give the range for $B\to\pi K$ decays, and for the system of $B_d\to\pi^+\pi^-$, $B_s\to K^+K^-$ modes.
