Fractional Effective Quark‐Antiquark Interaction in Symplectic Quantum Mechanics
Advances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023 Considering the formalism of symplectic quantum mechanics, we investigate a two‐dimensional nonrelativistic strong interacting system, describing a bound heavy quark‐antiquark state. The potential has a linear component that is analyzed in the context of generalized fractional derivatives.

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.

SPECULATIONS IN HADRON SPECTROSCOPY [PDF]
Spin 2004, 2005 A selected survey is presented of the recent progress in hadron spectroscopy. This includes spin-singlet charmonium states, excitations of charmonium and open-charm mesons, double-charm baryons, and pentaquark candidates. Models proposing exotic bound states or resonances are reviewed.

LIGHT HADRON SPECTROSCOPY [PDF]
Lepton-Photon 01, 2002 Rapporteur talk at the Lepton-Photon Conference, Rome, July 2001: reviewing the evidence and strategies for understanding scalar mesons, glueballs and hybrids, the gluonic Pomeron and the interplay of heavy flavours and light hadron dynamics. Dedicated to the memory of Nathan Isgur, long-time collaborator and friend, whose original ideas in hadron ...

Three-particle Lellouch-Lüscher formalism in moving frames
Journal of High Energy Physics, 2023 A manifestly relativistic-invariant Lellouch-Lüscher formalism for the decays into three identical particles with no two-to-three transitions is proposed.

La Rivista del Nuovo Cimento, 2010 In the past few years the field of hadron spectroscopy has seen renewed interest due to the pubblication, initially mostly from B-Factories, of evidences of states that do not match regular spectroscopy, but are rather candidates for bound states with additional quarks or gluons.
