Combined Evidence for the Boson After PADME Results on Resonant Production in Positron Annihilation
Fernando Arias-Aragón, Giovanni Grilli di Cortona, Enrico Nardi +1
The Positron Annihilation into Dark Matter Experiment at the Laboratori Nazionali di Frascati has reported an excess of final-state events from positron annihilation on fi…
Atoms as Electron Accelerators for New Physics Searches
Fernando Arias-Aragón, Giovanni Grilli di Cortona, Enrico Nardi +1
Due to Heisenberg's uncertainty principle, atomic electrons localized around the nucleus exhibit a characteristic momentum distribution that, in elements with high atomic number, r…
Bootstrap Your Own Context Length
Liang Wang, Nan Yang, Xingxing Zhang +2
We introduce a bootstrapping approach to train long-context language models by exploiting their short-context capabilities only. Our method utilizes a simple agent workflow to synt…
Axion-induced pair production: a new strategy for axion detection
Fernando Arias-Aragón, Maurizio Giannotti, Giovanni Grilli di Cortona +1
We revisit and update the axion-induced pair production process in a nuclear electric field mediated by the axion-electron coupling, $a+{{}^{A}_{Z}X} \rightarrow {{}^{A}_{Z}X} + e^…
