LiNeS: Post-training Layer Scaling Prevents Forgetting and Enhances Model Merging

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Nikolaos Dimitriadis, Alessandro Favero, Guillermo Ortiz-Jimenez, Francois Fleuret | Summary: Fine-tuning pre-trained models has become the standard approach to endow them with specialized knowledge, but it poses fundamental challenges. In particular, textit{(i)} fine-tuning often leads to catastrophic forgetting, where improvements on a target domain degrade […]

Ion manipulation from liquid Xe to vacuum: Ba-tagging for a nEXO upgrade and future $0 νββ$ experiments

Posted by klaurent Stanford

Kavli Affiliate: Giorgio Gratta | Summary:Neutrinoless double beta decay ($0νββ$) provides a way to probe physics beyond the Standard Model of particle physics. The upcoming nEXO experiment will search for $0νββ$ decay in $^136$Xe with a projected half-life sensitivity exceeding $10^28$ years at the 90% confidence level using a liquid xenon (LXe) Time Projection Chamber […]

Posted by klaurent Chicago

Kavli Affiliate: Clarence Chang | Summary:We describe observations of low energy excess (LEE) events, background events observed in all light dark matter direct detection calorimeters, and noise in a Transition Edge Sensor based two-channel silicon athermal phonon detector with 375 meV baseline energy resolution. We measure two distinct LEE populations: “shared” multichannel events with a […]

Universality in the Near-Side Energy-Energy Correlator

Posted by dbos Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Xiaohui Liu, Werner Vogelsang, Feng Yuan, Hua Xing Zhu, | Summary: We investigate the energy-energy correlator (EEC) of hadrons produced on the same side in $e^+e^-$ annihilation or in leading jets in $pp$ collisions. We observe a remarkable universality of the correlator. Using a non-perturbative transverse momentum […]
