Theoretical and Experimental Constraints in the $\mu$--$\tau$ Four-Lepton Sector of the SMEFT: implications to neutrino self interactions

Aadarsh Singh, G. D'Ambrosio, Sudhir K. Vempati · 2026

We study the dimension-six SMEFT four-lepton operators in the $\mu$--$\tau$ sector. These operators control both charged-lepton scattering and neutrino self-interactions, the latter being weakly const…

Local tensor-train surrogates for quantum learning models

Sreeraj Rajindran Nair, Christopher Ferrie · 2026

A key bottleneck in quantum machine learning is the computational cost of repeated quantum circuit evaluations during the inference phase. To address this, we present a framework for constructing fast…
