第五届JUNO相关的理论和唯象研讨会：首个物理成果专题研讨会

So far, the Gallium Anomaly has been observed only in Ga detectors, which makes it impossible to distinguish between systematic errors due to the detection method (e.g. as an overestimation of the neutrino absorption cross section) and other causes, such as errors in the estimation of the source activity or sterile neutrino.

It would be possible to test this anomaly in JUNO, detecting...

Neutrino signals can also be seen in dual-phase liquid-xenon TPCs. In this talk, we present the recent progress of solar neutrino studies in XENONnT dark matter experiment.

We developed an automatic renormalization group equations (RGEs) solver, D7RGESolver, designed for the precise numerical solution of one-loop RGEs of dimension-7 (dim-7) operators within the standard model effective field theory (SMEFT). This tool is capable of calculating the RGE effects of dim-5 and dim-7 SMEFT operators between any two scales above the electroweak scale. We then apply this...

The first results from the JUNO reactor neutrino oscillation experiment improve our knowledge of neutrino masses and mixing parameters, especially the solar angle and the solar mass squared difference . We discuss the implications of these results on neutrinoless double beta decay by itself and in combination with the global fit of neutrino oscillation experiments, the JUNO first data, and...

We compute electromagnetic radiative corrections in the inverse beta decay, ν¯e+p→e++n, at reactor antineutrino energies within the heavy baryon chiral perturbation theory, provide the most accurate cross-section predictions for this process, and present a complete error budget. For the first time, we consistently include quantum electrodynamics, chromodynamics, and electroweak contributions...

Terrestrial matter effects are small but non-negligible for JUNO-like medium-baseline reactor antineutrino program, at a level relevant to percent- to per-mille–precision determinations of the solar oscillation parameters and to the robustness of the mass-ordering measurement. In this talk I will discuss: the expected size of matter-induced spectral distortions and their impact on fits of key...
