91. Status and physical program of the vGeN experiment at Kalinin NPP

Alexey Konovalov (LPI RAS)

9/3/26, 3:25 PM

WG2: Neutrino Scattering Physics

Oral contribution

The vGeN ("nu-GeN") setup is collecting data at Kalinin NPP, 11.1 m from the center of a 3.1 GW reactor core, since late 2019. The aim of the experiment is to measure coherent elastic antineutrino-nucleus scattering (CEvNS) as well as to search for antineutrino electromagnetic properties with a 1.4 kg germanium point-contact detector. The talk presents updated results of the experiment on...

78. CICENNS experiment: A 300kg CsI(Na) detector for CEvNS measurement

宋天资 (Tianzi Song) (Sun Yat-sen University)

9/3/26, 3:50 PM

WG2: Neutrino Scattering Physics

Oral contribution

Coherent elastic neutrino-nucleus scattering (CEvNS) benefits from the coherent interaction of neutrinos with an entire nucleus at low momentum transfer, resulting in an enhanced cross section that provides a sensitive approach for detecting low-energy neutrinos. The CICENNS (CsI Detector for Coherent Elastic Neutrino-Nucleus Scattering) experiment aims to perform a high-precision measurement...

46. Exploring the electromagnetic properties of neutrinos at a short-baseline reactor neutrino experiment

Luis A. Delgadillo (IHEP)

9/3/26, 4:15 PM

WG2: Neutrino Scattering Physics

Oral contribution

Upcoming and present reactor neutrino experiments offer a compelling avenue to probe fundamental neutrino properties beyond flavor oscillations. In this talk, I will discuss the physics potential of a short-baseline reactor experiment, inspired by the JUNO-TAO configuration, to investigate neutrino electromagnetic interactions via electron--neutrino elastic scattering (E$\nu$ES). I will...

66. Neutrino Effects on Atomic Measurements of the Weinberg Angle

Bingrong Yu (Cornell University)

9/3/26, 4:40 PM

WG5: Neutrinos Beyond PMNS

Oral contribution

Atomic parity violation (APV) provides a unique determination of the weak mixing angle ($\sin^2\theta_W$) at low energies and therefore serves as a powerful precision test of the Standard Model. We show that previous APV calculations omitted a class of one-loop contributions arising from two-neutrino exchange, commonly referred to as "the neutrino force". We compute this contribution to APV...
