This #CMSPaper measures interactions between photons and Z bosons (quantum particles of electromagnetism and weak force). And measures if there are effects that explain why our universe contains more matter than antimatter. It's the most sensitive result for that signature arxiv.org/abs/2601.14102

To accurately reconstruct all particles in LHC collision, CMS uses a technique called "Particle Flow". This #CMSPaper shows how the newest, #machinelearning based particle flow algorithm performs in recent data and how well it does at rejecting extra uninteresting collisions arxiv.org/abs/2601.17554

Are there heavy undiscovered particles that decay to two Higgs bosons? This #CMSPaper describes the world most sensitive analysis, but we didn't discover any new particles in that signature. We only used data collected up to 2018 though... so more to come! https://arxiv.org/abs/2601.20011

Is there a fourth lepton and we just didn't see it because of the very tight online selection that detectors like CMS typically apply? This #CMSPaper uses the 'no cuts' scouting data to search for such leptons, assuming they behave a bit like a tau lepton, but heavier! https://arxiv.org/abs/2601.20063

How quarks cluster together into hadrons is only partially understood. With heavy quarks it is easier to calculate and measuring bound bottom quark-antiquark pairs is therefor super important to understand this aspect of the strong force. This #CMSPaper measures the Upsilon particles https://buff.ly/p5QZ00p

Experiments like CMS need algorithms called a trigger to decide which of the ~ 1 in 1000 events they want to keep (the other 999 are thrown away). This #CMSPaper describes the #machinelearning that is needed to do that for tau leptons https://arxiv.org/abs/2602.11359

This is a big one: the #CMSPaper summarising all precise Higgs boson measurements on data collected in 2016, 2017 and 2018. We agree with the standard model prediction for the total number of Higgs bosons, within 5-6% those are still big uncertainties for particle physics) https://arxiv.org/abs/2602.18611

This #CMSPaper measures for the first time the wake (yes, really, the wave created) from particles traversing the quark gluon plasma, a special form of matter (like gas, liquid, solid, etc. ), and it exists very shortly in the heavy ion collisions of the LHC https://arxiv.org/abs/2602.19431

The Higgs field has links to the evolution of the universe. And di-Higgs production is one of the most important ways to measure it in the coming years, and this #CMSPaper summarises where ATLAS and CMS together (yes, together 🤲) stand with the data collected up to 2018 https://arxiv.org/abs/2602.23991

There are many predictions for undiscovered particles that are similar to the Higgs particle. This #CMSPaper looks for the double whammy: two different undiscovered Higgs-like particles! It is the first time this was done. We didn't see anything but also used limited data https://arxiv.org/abs/2602.00273

This paper measures the polarisation of gluons within particle cascades. It turns out that the quantum particle of the strong nuclear force needs to be modelled with polarisation to reproduce the data. This #CMSPaper is important for understanding the strong nuclear force https://arxiv.org/abs/2603.03689

When a b quark turns into a c quark, and that charm quark shows up in a D meson with a light quark, that signature is called "open charm". This #CMSPaper measures how often that happens, which is important to understand how quarks stick together into particles https://arxiv.org/abs/2602.10270

The properties of the quark gluon plasma, a blob of matter created in LHC heavy ion collisions (and also present in stars) can be measured through angles between quarks and photons. This #CMSPaper does that, for the first time ever. This will help improve the calculations https://arxiv.org/abs/2602.18279

The strong force is particularly poorly understood (so, it's extremely difficult to calculate things) in the high-speed sprays consisting of soft particles we call jets. This #CMSpaper studies the behaviour of the particles inside jets to help improve those calculations https://arxiv.org/abs/2602.17509

The W boson can decay to leptons (which is how the super-precise W boson mass measurements are done), but most W bosons decay into quarks. Because we know the mass super accurately, this #CMSPaper uses the known W mass to better understand the way quarks from W bosons decay (and how they overlap at high speeds) by measuring the W boson mass in high mometum particle jets https://arxiv.org/abs/2603.19963

Top quarks are usually produced in quark-antiquark pairs, but through the weak interaction, it is possible to create single top quarks too. This #CMSPaper measures one of the single top quark production modes, and provides important input to measure and understand quantum fluctuations inside protons, particularly of b quarks.

This #CMSPaper looks for the signature of massive hypothetical particles that have connections to dark matter, quantum gravity and supersymmetry. We didn't see any, but these particles would also be super-rare if they exist (only a handful produced over many years). It is a #NullResult https://arxiv.org/abs/2603.11035

Are there undiscovered particles being produced at the LHC that we just missed? This #CMSPaper looks for such long-lived particles. Understanding the detector is very important there as known particles can make that signature when they traverse the material of our detector arxiv.org/abs/2511.08212

Do particles with one strange quark and one light quark get stopped or change direction by the quark-gluon blob created in the lead collisions of the LHC when it is in heavy-ion mode? This #CMSPaper measures that these medium-sized particles don't feel the quark gluon plasma https://arxiv.org/abs/2602.14221

Are there undiscovered particles that decay to a Higgs boson and a photon? Or a Z boson and a photon? (at high momentum it's difficult to see the difference between a Higgs boson and a Z boson) This #CMSPaper looks for a very massive resonance from such a particle. arxiv.org/abs/2511.14583

This paper measures the polarisation of gluons within particle cascades. It turns out that the quantum particle of the strong nuclear force needs to be modelled with polarisation to reproduce the data. This #CMSPaper is important for understanding the strong nuclear force and to improve particle collision simulations https://arxiv.org/abs/2603.03689

This #CMSPaper looks for diphoton resonances at low(ish) mass. There are some non-significant excesses here, but beware, diphoton events are notoriously sensitive to statistical fluctuations (remember #750GeV) https://arxiv.org/abs/2603.03250

Measuring the Higgs field can be done (indirectly) through the measurement of the interaction of the Higgs boson with itself and has links to the evolution of the universe. This is why di-Higgs production is one of the most important targets of the LHC in the coming years, and this #CMSPaper summarises where ATLAS and CMS together (yes, together 🤲) stand with the data collected up to 2018 https://arxiv.org/abs/2602.23991

This #CMSPaper presents a systematic study of how particles lose energy (and how many particles are stopped ) when traversing the (very tiny, but very dense) hot mess that forms at the LHC collision point. Comparing different collision types (lead, oxygen, etc) helps guide what we should collide next in future nuclear physics programs at the LHC https://arxiv.org/abs/2602.21325

The top quark is super heavy, and we don't know why. Is it maybe a composite (particle made of other particles)? This #CMSPaper is looking if there are excited states of top quarks created at high mass, this would be one of the signs of composite top quarks. We didn't see anything, but also very limited data still https://arxiv.org/abs/2602.20477

This #CMSPaper measures for the first time the wake (yes, really, the wave created) from particles traversing the quark gluon plasma. The quark gluon plasma is a special form of matter (like gas, liquid, solid, etc. ), and it exists very shortly in the lead collisions of the LHC in heavy ion mode https://arxiv.org/abs/2602.19431

In super rare cases, the collisions in the large hadron collider are not between protons or ions, but between photons! (because protons&ions sometimes create photons) This #CMSPaper #discovers for the first time that W bosons (2 of them) are created in such photon-fusion collisions https://buff.ly/ej68FJd
