Contributions of K0∗1430 and K0∗1950 in the Charmed Three‐Body B Meson Decays
Advances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023 In this work, we investigate the resonant contributions of K0∗1430 and K0∗1950 in the three‐body B(s)⟶D(s)Kπ within the perturbative QCD approach. The form factor Fkπ(s) is adopted to describe the nonperturbative dynamics of the S‐wave Kπ system. The branching ratios of all concerned decays are calculated and predicted to be in the order of 10−10 to 10−

INCREASE: An updated model suite to study the INfluence of Cosmic Rays on Exoplanetary AtmoSpherEs
Astronomische Nachrichten, Volume 343, Issue 4, May 2022., 2022 Abstract Exoplanets are as diverse as they are fascinating. They vary from ultrahot Jupiter‐like low‐density planets to presumed gas‐ice‐rock mixture worlds such as GJ 1214b or worlds as LHS 1140b, which features twice the Earth's bulk density. Regarding the great diversity of exoplanetary atmospheres, much remains to be explored.

Access to the Kaon Radius with Kaonic Atoms
Annalen der Physik, Volume 534, Issue 3, March 2022., 2022 Herein, a method to determine the kaon radius from the spectra of kaonic atoms by analyzing the few lowest‐lying transitions in a wide nuclear charge range is proposed, taking into account leading‐order QED and nuclear‐size effects. Additionally, the opportunities for extracting the kaon mass and nuclear radii are demonstrated.

Optical Excitation of Ultra‐Relativistic Partially Stripped Ions
Annalen der Physik, Volume 534, Issue 3, March 2022., 2022 Implementation of the Gamma Factory (GF) requires identification of ions to be accelerated and stored. It also necessitates development of schemes of ions' efficient excitation. Here, the first systematic studies of the most promising candidates and excitation schemes are presented, providing realistic estimates of energy and flux of GF‐emitted photons.

Expanding Nuclear Physics Horizons with the Gamma Factory
Annalen der Physik, Volume 534, Issue 3, March 2022., 2022 The Gamma Factory is an ambitious proposal for a source of photons with energies up to hundreds of MeV and photon fluxes exceeding those of the currently available gamma sources by orders of magnitude. The paper surveys the new opportunities in nuclear physics and related fields that may be afforded by the this facility. Abstract The Gamma Factory (GF)

Exotic Hadron Spectroscopy [PDF]
EPJ Web of Conferences, 2014 Since ten years ago experiments have been observing a host of exotic states decaying into heavy quarkonia. The interpretation of most of them still remains uncertain and, in some cases, controversial. Notwithstanding, a considerable progress has been made on the quality of the experimental information available and a number of ideas and models have ...

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 A difference in electric potential in a static conductor inside a static magnetic field and an anisotropic and asymmetric distribution of neutrons emitted in nuclear reactions induced by ultrasound are assumed as marks of local Lorentz invariance (LLI) violation.

Hadronic Molecule Interpretation of Tcc+ and Its Beauty Partners
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 Motivated by the latest discovery of a new tetraquark Tcc+ with two charm quarks and two light antiquarks by LHCb Collaboration, we investigated the DD∗ hadronic molecule interpretation of Tcc+. By calculation, the mass and the decay width of this new structure Tcc+ can be understood in one‐meson exchange potential model. The binding energies for these
