Tänään käytin noin kolme tuntia lukien noin kaksi sivua 1709 renovoidusta tuomiokirjasta. Renovoidut kirjat siis puhtaaksikirjoitettuja, eli selkeitä. Alkaa tuntua siltä, ettei 1700-luvun virkamiesruotsin lukeminen ole enää mahdotonta. Työlästä, muttei mahdotonta. #sukututkimus

"Moni noro tai puro on vuosien saatossa joutunut jollain lailla ihmisen toimien kohteeksi. Ihaksin ja Halmeen mukaan vesilaki pitäisi uudistaa niin, että noro olisi aina jollain tavalla turvattu riippumatta sen tilasta." yle.fi/a/74-20192053

We don't see the decay of the Higgs boson to charm quarks (yet!), but it is also possible to measure the interaction of the Higgs boson with charm by studying those particles being produced together. This #CMSPaper studies that Higgs+charm signature (we don't see it yet): arxiv.org/abs/2508.14988

Here we see the Alpha Magnetic Spectrometer (AMS) detector. Most recently upgraded in 2024, it searches for dark-matter signatures from cosmic rays, #antimatter, and missing matter from its position on the exterior of the International Space Station.

This #CMSpaper looks again at a non-significant (but intriguing!) excess in signatures consistent with two unstable, unknown particles from a heavier source. This paper further compares to theory predictions explaining these four-jet events arxiv.org/abs/2507.17884

This #CMSPaper explores the excitation of three particles with a B quark and other quark, examining how they store extra energy beyond the ground state. It marks the first simultaneous measurement of these particles. This improves knowledge of particles that contain quarks arxiv.org/abs/2508.05820

Are there undiscovered particles that decay to a Higgs boson and something else? This #CMSPaper describes how we scanned the invariant mass spectrum, but did not find any signs (in very very few events, and this should be rare. We will do this again when we have more data) arxiv.org/abs/2508.11494

Mitä eroa on pienimmillä tähdillä ja suurimmilla planeetoilla? Miksei pienimpiä tähtiä kierrä juurikaan suuria planeettoja? Valtaosalla tähdistä ei ole kaasujättiläisiä kiertolaisinaan, ja punaisilla kääpiötähdillä on niitä seuranaan vielä harvemmin, Mikko Tuomi @mustapipa.bsky.social kirjoittaa. 🔭

The LHC produces a large number of Z bosons. So it is worthwhile checking if some of them behave inconsistently with the standard model. This #CMSPaper measured that the chance that Z bosons decay to two different kinds of leptons is smaller than one in 10 million arxiv.org/abs/2508.07512

Are there undiscovered particles (that are very light for LHC standard) produced in Higgs boson decays? This #CMSPaper describes how we look for them, but did not see any arxiv.org/abs/2508.06947

Are there invisible (and long-lived) undiscovered particles produced in the decays of B mesons? Those would be super rare, so we use a huge dataset of B mesons with dedicated data taking techniques. We didn't see any new particles though, this #CMSPaper is a #nullresult arxiv.org/abs/2508.06363

If you need a reference model of what an extension of the standard model with many new particles would look like, Supersymmetry is a good benchmark. This #CMSPaper shows a general search in many standard signatures, looking for deviations spread over different signatures arxiv.org/abs/2508.13900

In fact it is already happening. The tropical coral reefs are past their tipping point, mass bleaching is widespread. 😢

Guterres is right. Even a temporary overshoot could unleash far greater destruction and costs for every nation. It could push ecosystems past catastrophic and irreversible tipping points. Fossil fuel companies are deceiving the public and obstructing progress. www.theguardian.com/environment/...

The production of the Higgs boson along with an undiscovered hypothetical particle is an important signature for detecting physics beyond the standard model. This #CMSPaper looks for the "Higgs boson+jet not consistent with the standard model" signature (we didn't see any): arxiv.org/abs/2509.13635

Apua ei tahdo saada -- mutta apua saavat ovat tyytyväisiä palveluihin. Monien elämässä on erittäin syvällisiä haasteita -- mutta Suomi on silti maailman paras maa elää. Selvä. Tai siis ei yhtään selvä. #yhteiskunta

Can you guess any of these experiments and what they all have in common? Hint: they do some heavy detective work😉 Here we see parts of nine CERN experiments that hunt for #DarkMatter by studying different physics.

The first tray, assembled at Peking University, has arrived at CERN in late September! The BTL team was eager to unbox the tray, packaged in a wooden crate, padded with foam, suspended on vibration damping feet and wrapped in anti-static foil. 🏆 MTD Image of the Month 📸 Nefeli Stathaki

The LHC recently collided oxygen ions, and this #CMSPaper shows that we see charged particle suppression , a telltale sign that these collisions are creating the quark gluon plasma: arxiv.org/abs/2510.09864

The production of top quark pairs together with a W boson is a great way to test the quality of standard model predictions. This #CMSPaper measures provides boundaries on things like the difference between ttW+/- production, a very sensitive quantity to test the predictions arxiv.org/abs/2509.13512

First observation of single top quark production with W and Z bosons This incredibly rare phenomenon, observed at the @cmsexperiment.bsky.social, can help probe the fundamental forces of nature. Find out more: home.cern/news/news/ph...
