4. Forming molecular states with hadronic rescattering

   Abstract A method for modelling the prompt production of molecular states using the hadronic rescattering framework of the general-purpose Pythia event generator is introduced. Production cross sections of possible exotic hadronic molecules via hadronic rescattering at the LHC are calculated for the$$\chi _{c1}(3872)$$ ${\chi }_{c1}\left(3872\right)$resonance, a possible tetraquark state, as well as three possible pentaquark states,$$P_c^+(4312)$$ $P_c^{+}\left(4312\right)$,$$P_c^+(4440)$$ $P_c^{+}\left(4440\right)$, and$$P_c^+(4457)$$ $P_c^{+}\left(4457\right)$. For the$$P_c^+$$ $P_c^{+}$states, the expected cross section from$$\Lambda _b$$ ${\Lambda }_b$decays is compared to the hadronic-rescattering production. The$$\chi _{c1}(3872)$$ ${\chi }_{c1}\left(3872\right)$cross section is compared to the fiducial$$\chi _{c1}(3872)$$ ${\chi }_{c1}\left(3872\right)$cross-section measurement by LHCb and found to contribute at a level of$${\mathcal {O}({1\%})}$$ $O\left(1\%\right)$. Finally, the expected yields of$$\mathrm {P_c^{+}}$$ $P_c^{+}$production from hadronic rescattering during Run 3 of LHCb are estimated. The prompt background is found to be significantly larger than the prompt$$\mathrm {P_c^{+}}$$ $P_c^{+}$signal from hadronic rescattering.

5. Learning molecular potentials with neural networks

   https://doi.org/10.1002/wcms.1564  

   Gokcan, Hatice; Isayev, Olexandr (July 2021, WIREs Computational Molecular Science)

   Abstract The potential energy of molecular species and their conformers can be computed with a wide range of computational chemistry methods, from molecular mechanics to ab initio quantum chemistry. However, the proper choice of the computational approach based on computational cost and reliability of calculated energies is a dilemma, especially for large molecules. This dilemma is proved to be even more problematic for studies that require hundreds and thousands of calculations, such as drug discovery. On the other hand, driven by their pattern recognition capabilities, neural networks started to gain popularity in the computational chemistry community. During the last decade, many neural network potentials have been developed to predict a variety of chemical information of different systems. Neural network potentials are proved to predict chemical properties with accuracy comparable to quantum mechanical approaches but with the cost approaching molecular mechanics calculations. As a result, the development of more reliable, transferable, and extensible neural network potentials became an attractive field of study for researchers. In this review, we outlined an overview of the status of current neural network potentials and strategies to improve their accuracy. We provide recent examples of studies that prove the applicability of these potentials. We also discuss the capabilities and shortcomings of the current models and the challenges and future aspects of their development and applications. It is expected that this review would provide guidance for the development of neural network potentials and the exploitation of their applicability.
