Measurement of Born Cross Section for at GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +759
Using collision data collected with the BESIII detector at the BEPCII collider corresponding to a total integrated luminosity of 44~fb, we present the first measure…
First Measurement of the Relative Phase between Proton Psionic Form Factors
BESIII Collaboration, M. Ablikim, M. N. Achasov +754
The relative phase between the time-like form factors of the proton is a crucial observable for a complete understanding of its internal structure, yet it has remained unmeasured d…
Proof of principle for nucleon polarization measurement at BESIII
BESIII Collaboration, M. Ablikim, M. N. Achasov +754
A novel technique for measuring the spin polarization of final-state nucleons in a general-purpose spectrometer is validated. Using events at BESIII, the…
TriAgent: Divergence-Aware Multi-Agent Committees for Cost-Efficient Financial Sentiment Analysis
Isabel Xu, Cynthia Xu, Rachel Ren +2
Production LLM-based financial sentiment analysis faces a structural cost trap: most queries are trivially classifiable, yet expensive cloud reasoners process them all, and the bil…
Information Propagation and Contraction in Functional Interpretations
Chuangjie Xu
This paper separates two components of functional interpretations: affine information propagation and contraction. We introduce information nuclei as an algebraic interface to capt…
