Amplitude analysis of the B+→D+D−K+ decay

Physical Review D - Particles, Fields, Gravitation and Cosmology. 2020. Vol. 102. No. 11. Article 112003.
Aaij R., Beteta C. A., Arzymatov K., Belavin V., Boldyrev A., Borisyak M., Derkach D., Гайнцева Т. А., Hushchyn M., Kazeev N., Maevskiy A., Ratnikov F., Ryzhikov A., Ustyuzhanin A., Филиппов А. А., LHCb C.

Results are reported from an amplitude analysis of the B+→D+D−K+ decay. The analysis is carried out using LHCb proton-proton collision data taken at √s=7, 8, and 13 TeV, corresponding to a total integrated luminosity of 9  fb−1. In order to obtain a good description of the data, it is found to be necessary to include new spin-0 and spin-1 resonances in the D−K+ channel with masses around 2.9  GeV/c2, and a new spin-0 charmonium resonance in proximity to the spin-2 χc2(3930) state.

Kolokolov I., Lebedev V., Physical Review E - Statistical, Nonlinear, and Soft Matter Physics 2026 Vol. 113 Article 054117
We theoretically investigate the correlation functions of the phase of a light wave propagating through a turbulent medium. We use an equation for the logarithm of a wave packet envelope, which includes a secondorder nonlinear term. Based on this equation, we develop a diagrammatic technique to calculate corrections to the correlation function obtained in the linear approximation. We ...

Heterostructures based on ZnO nanorods and CsPbBr3 nanocrystals were investigated for their potential as semiconductor SERS substrates. We found that ZnO morphology governs the efficiency of interfacial energy transfer, leading to enhanced photoluminescence under 390 nm excitation and a noticeable reduction of the bandgap in the composites. Raman analysis revealed a pronounced intensity enhancement and ...

Wave propagation and transformation in the frame of magnetohydrodynamics with a vortex electric field
Bisnovatyi-Kogan G., Kondratyev I., Moiseenko S. G., International Journal of Modern Physics A 2025 Vol. 40 No. 7 Article 2550018
Bright transient objects in different wave bands have been discovered in recent years. To explain these short (from ms to s), and very powerful events, different models, galactic and extragalactic, have been considered. One of the popular models is based on the suggestion of transformation of the magnetized plasma blob, presumably a magnetohydrodynamic (MHD) shock wave, moving with relativistic ...

The influence of asymmetry of plasma sources on the structure and spatial localization of a superthin current sheet (STCS) supported by demagnetized electrons is studied using a self-consistent model. The simulation takes into account the presence of a single plasma source in the northern hemisphere, which makes the plasma flow asymmetric. It is demonstrated that the asymmetry of ...

Stable Multi-Wavelength Resonant Metal-dielectric Hybrid Nanostructure in the Infrared Range
Lu X., Tognazzi A., Klimov V. et al., Plasmonics 2026 Vol. 21 P. 1503–1512
Plasmonic nanostructures typically exhibit shifts in their resonant wavelength in response to changes in the refractive index of the surrounding medium. This limits their applications in scenarios requiring stable optical resonances. Here we present a metallic-dielectric hybrid metasurface that exhibits stable multi-wavelength resonance even if the refractive index of its surrounding varies. To quantitatively evaluate the stability of ...

Cross-influence of two societies in deterministic evolutionary game

We present a simple model that simulates the possible influence of one society on another. Specifically, two societies evolve deterministically according to the well-known Nowak-May spatial game with the addition of mutual influence through connections that reflect the current states of the societies. This may be related to the influence of a global information resource ...

Ising models on the hydrogen peroxide and other lattices
Qin X., Deng Y., Shchur L. et al., / Series arXiv "math". 2026. No. 2603.02962.
We perform a Monte Carlo analysis of the Ising model on many three-dimensional lattices. By means of finite-size scaling we obtain the critical points and determine the scaling dimensions. As expected, the critical exponents agree with the three-dimensional Ising universality class for all models. The irrelevant field, as revealed by the correction-to-scaling amplitudes, appears to ...
