Intramolecular Hydrogen Bond Energy and Its Decomposition—O–H∙∙∙O Interactions
Crystals, 2020 The method to calculate the energy of intramolecular hydrogen bond is proposed and tested for a sample of malonaldehyde and its fluorine derivatives; the corresponding calculations were performed at the ωB97XD/aug-cc-pVTZ level.

The $\eta$- and $\eta'$-nucleus interactions and the search for $\eta$, $\eta'$- mesic states
, 2020 The isoscalar $\eta$ and $\eta'$ mesons are special in QCD, being linked both to chiral symmetry and to non-perturbative glue associated with the axial anomaly. The properties of these mesons in medium are sensitive to how these dynamics work in the nuclear environment.

Molecules, 2020 Various Lewis acid–Lewis base interactions are discussed as initiating chemical reactions and processes. For example, the hydrogen bond is often a preliminary stage of the proton transfer process or the tetrel and pnicogen bonds lead sometimes to the SN2

Eta and eta’ physics in KLOE [PDF]
EPJ Web of Conferences, 2019 We present results obtained by the KLOE Collaboration at the DAфNE e+e− collider located in Frascati Laboratories, Italy. The results concern precise measurements of several η meson decays such as Dalitz slope parameters and charge asymmetries for $ \eta \to \mathop \pi \nolimits^ + \mathop \pi \nolimits^ - \mathop \pi \nolimits^0 $, branching ratio

Search for the X (2370) and observation of eta(c) -> eta eta eta ' in J/psi -> gamma eta eta eta '
, 2021 Using a sample of 1.31 x 10(9) J/psi events collected with the BESIII detector, we perform a study of J/psi -> gamma eta eta eta' to search for the X(2370) and eta(c) in the eta eta eta' invariant mass distribution. No significant signal for the X(2370) is observed, and we set an upper limit for the product branching fraction of B(J/psi -> gamma X(2370)

Académicos en el punto de mira. La violencia de eta y su entorno contra la universidad (1995-2011)
Studia Historica: Historia Contemporánea, 2023 La estrategia denominada «socialización del sufrimiento» comienza en 1995 con el asesinato de Gregorio Ordóñez. También en este momento las universidades del País Vasco y de Navarra vieron cómo la amenaza de ETA se cernía sobre ellas.
