This paper validates a Long Short-Term Memory (LSTM) neural network approach that successfully identifies jet quenching in heavy-ion collisions by leveraging jet substructure and parton shower history, demonstrating robust performance even when accounting for detector effects and generalizing to untrained observables.
The CMS experiment reports the first measurement of the inclusive top quark pair production cross section in lead-lead collisions at = 5.36 TeV, finding results consistent with next-to-next-to-leading order perturbative QCD predictions and providing the first investigation of top quark production dependence on collision impact parameter.
This study reveals that surrogate reactions used to study Pu(n,f) exhibit hindered prompt-neutron evaporation due to entrance-channel-induced angular momentum, highlighting significant limitations in applying surrogate-derived data to nuclear technology.
Using an extended isospin- and momentum-dependent Boltzmann-Uehling-Uhlenbeck transport model, this study demonstrates that incorporating momentum dependence in the nuclear mean field is essential for accurately reproducing STAR experimental data on proton, kaon, and production in Au+Au collisions at GeV, whereas momentum-independent models only partially describe the results.
This paper presents the first calculation of next-to-next-to-leading order (NNLO) QCD radiative corrections for deeply virtual pion production, demonstrating that these two-loop corrections substantially improve the agreement between perturbative QCD predictions and experimental data from JLab while also refining theoretical descriptions of transverse single-spin asymmetries for future facilities like the EIC and EicC.
This article presents a vision for the emerging era of rare isotope beam science, emphasizing the critical integration of theoretical, computational, and experimental advances to explore exotic nuclei near drip lines and their connections to nuclear astrophysics.
This paper proposes using time modulation in weak nuclear decays as a probe for axion dark matter, deriving a theoretical framework to predict such variations, constraining axion parameters using existing Gran Sasso data on K and Cs, and suggesting a new electron capture measurement to extend sensitivity to higher axion masses.
This paper demonstrates that while global multiplicity fluctuations introduce a constant vertical offset in the differential radial flow observable , only the shape of this distribution (or its derivative) contains genuine physical information about radial-flow dynamics, rendering its zero-crossing point physically insignificant.
This contribution employs principal component analysis to decompose event-by-event spectral fluctuations in heavy-ion collisions into distinct thermal and geometric normal modes, establishing a physical analogy to molecular vibrations that explains key experimental observables such as and the sign change at low in .
Motivated by applications in neutrino mass experiments and precision spectroscopy, this paper presents calculations of energy-dependent elastic scattering cross sections for hydrogen, deuterium, and tritium on helium isotopes, revealing that tritium scattering is significantly enhanced at low energies due to a near-threshold s-wave resonant bound state before converging to a geometric limit at higher energies.
