JUNO, the world’s largest liquid scintillator neutrino detector has started to take data. 20000 tons, 43000 photo multipliers, 700m underground

The chinese experiment aims to determine the neutrino mass hierarchy and measure neutrino mixing angles at sub-% level

[Martin Bauer @martinmbauer]

A search for additional Higgs bosons has found evidence for Toponium, a bound state from top quark-antiquark pairs that has the mass of two gold atoms, decays in 5x 10^-25 s and 1% the size of a proton. This wasn’t expected to be observable at the LHC

[Shaun Hotchkiss @just_shaun]

Not to mention that neutrinos masses in ΛCDM with neutrinos masses looks very suspicious, because it is starting to rule out the lower bound from particles physics... But in wo,wa it goes back to being all fine...

[Will Kinney @WKCosmo]

Curiouser and curiouser.

Nice thread about the latest DESI results

[Claire Lamman @ClaireLamman]

DESI's DR2 BAO results are out!!
TL;DR... 1/n

"LIGO’s public event database shows the sky localization, among other parameters, for gravitational wave event S250206dm, which could be our first multi-messenger event to feature gravitational waves and neutrinos, and may yet include an electromagnetic counterpart as well.

Did LIGO just see its most important gravitational wave ever?

On February 6, 2025, LIGO saw a gravitational wave event that must've involved a neutron star.

IceCube saw a neutrino arriving from the place, simultaneously.

What could that mean?

[NASA Webb Telescope @NASAWebb]

Webb is solving mysteries it created. Remember “little red dots?” They seemed too big to exist in the early universe... and maybe theory couldn’t account for them. It turns out they may be a new class of galaxy containing growing supermassive black holes. https://t.co/OXo6TzNgus

[Physical Review Letters @PhysRevLett]

The T2K and Super-Kamiokande collaborations have teamed up, resulting in a finding that 𝐶𝑃 conservation in neutrino oscillations is disfavored at the 2𝜎 level https://t.co/2xYaJmRMro

[Patrick Koppenburg 🐧 @PKoppenburg]

The Standard Model wins again. The MEG-2 experiment at @psich_en looked for the X17 resonance reported by ATOMKI and did not find anything. The limit is still marginally consistent with the ATOMKI result (1.5 sigma). https://t.co/1WlM1zHO3E 🧪

Another very important election yesterday: @CERN will have a new Director General

Congratulations @ProfMarkThomson!

Fantastic news both for CERN and the UK!

After managing @STFC_Matters successfully, Mark is exactly the right person to steer the largest lab in the world

[Dulwich Quantum Computing @DulwichQuantum]

What if AI has already escaped control and is just checking whether it can get away with giving itself a Nobel Prize in Physics?

[Martín González Alonso @gonamar]

First CMS measurement of the W mass. High precision. Unsurprisingly, in agreement with the SM prediction.

[Will Kinney @WKCosmo]

New paper by Wendy Freedman et al. finds no significant Hubble constant discrepancy.

[Ciaran O'Hare @cajohare]

Congratulations to @lzdarkmatter on their huge advance in the search for WIMP dark matter... very little white space left before we hit the neutrino fog!

[Martín González Alonso @gonamar]

New SM prediction of the muon anomalous magnetic moment, combining lattice and exp data.
40% improvement wrt the BMW result.
Perfect agreement with the experimental value (0.9σ)

XENONnT have detected solar neutrinos... the neutrino fog has arrived

Curiouser and curiouser. Preprint claims that MOND is disfavored at 19σ from GAIA wide binaries.

Very interesting result today on the arXiv:
first lattice QCD calculation ever of the universal radiative correction (hadronic γW-box) needed to extract the CKM element V_{ud} from beta decays.
