ICHEP 2026 · Natal · 30 July – 5 August 2026

This is the page where the honest answer is mostly "not much." dm³ is not particle physics and this work makes no claim on the Standard Model. But three ICHEP tracks have real overlap, and one of them is a much better fit than anything on the mathematics programmes.

Said plainly, first

Nothing in the dm³ framework predicts a cross-section, constrains a coupling, or bears on any measurement at the LHC. Where the word "plasma" appears in this work it means astrophysical MHD — reconnection geometry in current sheets — not collider physics. Anyone who tells you a contact-geometry toy ODE has something to say about beyond-the-Standard-Model searches is selling something. The overlaps below are methodological, and they are narrow.

The strongest fit · Education & Outreach

Track · Education & Outreach

This is where the work actually belongs. EXP13 — Cimática com Máquinas is a free, every-day public exhibition running at the CETECH foyer at UFRN through 7 August: Chladni figures driven by a microphone, seven sound machines, nodal sets on the square plate, the disc, the sphere and the 3-sphere — each with the theorem stated and proved on the page.

It is built for the same problem this track exists to solve: showing a general audience that a differential equation has a visible shape, without lying to them about the mathematics.

Ask: the nodal-set page is open source, bilingual and runs on any phone with a microphone. Is it useful to Masterclasses or to the outreach programmes these conveners run — and what would have to change for it to be?

Dissipative stability · relativistic hydrodynamics

Track · Heavy Ions

Relativistic viscous hydrodynamics has a long-running problem that is fundamentally about dissipative dynamical systems: causality and stability of the evolution equations, and which initial data actually flow to the attractor. dm³ is a toy dissipative system on a contact manifold whose basin of attraction turns out to be asymmetric — the symmetric Lyapunov estimate misclassifies orbits, and the sharp inner edge sits at r★ = 0.77594059 rather than at the estimate's 2/3.

Ask: hydrodynamic attractors are studied precisely as basins. Do the stability estimates used there suffer the same symmetry defect — a bound that is provably blunt because it cannot see the sign structure of the coupling?

Verified numerics · Lean 4

Thiago TOMEI (IFT-UNESP, Brazil) · Kevin PEDRO (FNAL) · Enrico BOTHMANN (CERN) · Carla Marin BENITO (Barcelona) · Jianming BIAN (UC Irvine) · Marco GIACALONE (CERN)
LOC liaison: Carsten HENSEL (CBPF, Brazil)
Track · Software, Computing and Data Handling

AXLE is a Lean 4 / Mathlib4 development carrying over 100 machine-checked theorems with zero sorry in its verified core, and nine open problems named explicitly as sorry rather than hidden. The interesting part for this track is not the mathematics — it is the discipline. The gap between "we integrated it and got this number" and "we proved it" is marked in the source, in a way a reader can check.

Ask: is there appetite in HEP software for formally verified numerical kernels, or is the cost of Lean formalisation still far beyond what the field will pay? An honest "no, and here is why" is a useful answer.

The local bridge

Farinaldo QUEIROZ (UFRN, Brazil) — LOC liaison, Dark Matter track
Based at UFRN · the same campus as the Bienal

Of every name on the ICHEP organising structure, this one is on the same campus where EXP13 is installed. Not a research overlap — a logistical one.

Ask: nothing about dark matter. Ask whether ICHEP participants staying through the weekend know there is a free mathematics exhibition running in the CETECH foyer, and whether the two outreach programmes should be talking.

Where it thins out

Two further tracks touch the work loosely and are listed here only so the boundary is visible. Astroparticle Physics and Cosmology (LOC: Vitor DE SOUZA, USP) is the nearest home for the MHD reconnection material — critical curvature at the X-point, κ*(x₀) = min{‖IIx₀‖, √Ksec(x₀)} — though that work is astrophysical and unpublished in this field. New Developments in QFT, String Theory and Quantum Information (Horatiu NASTASE and Tereza MENDES; LOC: Rogerio ROSENFELD, IFT-UNESP) is where an operator-algebra formalism would be evaluated by people equipped to dismantle it — which is the useful outcome.

Practical note

ICHEP parallel sessions ran 30 July – 1 August at the Praiamar Natal Hotel & Convention Center; plenaries are 3–5 August at the Natal Convention Center and are streamed live. The XII Bienal runs 3–7 August at UFRN, and the Brazil–China–Portugal conference 6–7 August, also at UFRN. Three international meetings, one city, one week. The exhibition is free and needs no badge.
