The 2030s: what\'s coming
Seven articles on the experiments that will define neutrino physics over the next decade. After this path you\'ll know which experiment will deliver which result, on what timescale, and how they all fit together.

Neutrino physics 2025: the year in review
14 minWhere the field stands at the start of 2026. KATRIN, DESI, JUNO, IceCube, T2K/NOvA, LEGEND-200 — what they have, what they haven't, and what each will do next.
Why this step: Sets the scene. After this, everything that follows is a deeper look at one piece.

JUNO watches from Jiangmen
10 minThe 20-kt liquid-scintillator reactor experiment in southern China. Starts physics 2026. Designed to determine the mass ordering at 3–4σ within six years.
Why this step: First major next-generation experiment to deliver results. Strong implications for the rest of the field.

Hyper-Kamiokande: Japan's next-generation detector
11 min260-kt water Cherenkov detector in the Kamioka mine. Five times larger than Super-K. First beam expected 2027.
Why this step: The other half of the global CP-violation effort with DUNE. Cleaner short-baseline geometry.

DUNE: underground experiment for the matter mystery
12 minThe 40-kt liquid-argon TPC at Sanford Lab, on the LBNF beam from Fermilab. 1300 km baseline. Wide-band beam. First module ~2028, full operation early 2030s.
Why this step: The technologically most ambitious neutrino experiment. Will determine δ_CP and mass ordering by ~2032.

IceCube-Gen2: 10× larger, more strings, more physics
10 min10 km³ of instrumented Antarctic ice, ten times the volume of current IceCube. Will detect the first cosmic neutrinos in radio at EeV energies. Mid-2030s start.
Why this step: The astrophysical-neutrino frontier through the 2030s.

The 0νββ ton-scale program
11 minLEGEND-1000 (Ge-76), nEXO (Xe-136), KamLAND2-Zen, CUPID. The 1-ton-scale 0νββ search that will probe whether neutrinos are Majorana for normal-ordering masses.
Why this step: The most direct path to discovering whether neutrinos are their own antiparticles.

CMB-S4 and cosmology's neutrino measurements
9 minThe 2030s CMB experiment that will tighten the cosmological bound on Σm_ν to ~0.04 eV. Combined with DESI, this is the precision frontier on absolute mass.
Why this step: Cosmology is now the most-stringent neutrino constraint. CMB-S4 will push it further.
