Today, we have the Standard Model of particles with four fundamental forces governing them. But things weren't always the way they are now.

#KnowledgeByte: The "#Ghost #Particle" observatory, officially known as the #IceCube Neutrino Observatory, is built in Antarctica because the region provides unique natural conditions necessary to detect elusive particles called neutrinos.

#paperOfTheDay for Tuesday: "Effective chiral Lagrangians for nucleon-pion interactions and nuclear forces" from 1991. This is one of the foundational papers of chiral effective field theory.
In principle, the interactions of nucleons (i.e. protons, neutrons), like any other interaction on small scales, is governed by the standard model of #particle physics, in particular #quantum chromodynamics. However, it is highly impractical to do calculations this way because below a certain energy (around 1GeV), the QCD force is so strong that it creates bound states, which one can not easily handle in perturbative #quantumFieldTheory . The way out is to use an effective field theory: The resulting objects, however they may arise, of course follow the usual laws of quantum mechanics, and they have certain symmetries governing their possible interactions. One takes these objects -- in the present case nucleons and pions -- as "elementary particles", writes down an ansatz for a Lagrangian, and works with this as usual.
In order to do perturbation theory, one needs a way to determine which terms are important and which are small corrections, and how the various terms scale under e.g. a change in energy. This "power counting" is more tricky in chiral effective theory than usual, because one has multiple mass scales and their ratios, but one possible way to do it is described in the paper.

Wake up babe, new particle just dropped.

Xi-cc-plus - four times heavier than the regular proton, behaves like a rubber band.

This is the first new particle identified after the upgrades to the LHCb detector that were completed in 2023, and only the second time a baryon with two heavy quarks has been observed, the first having being observed by LHCb almost 10 years ago. The result will help theorists test models of quantum chromodynamics, the theory of the strong force that binds quarks into not only conventional baryons and mesons but also more exotic hadrons such as tetraquarks and pentaquarks.”

LHCb Collaboration discovers new proton-like particle

The LHCb experiment at CERN’s Large Hadron Collider (LHC) has discovered a new particle consisting of two charm quarks and one down quark, a similar structure to the familiar proton, but with two heavy charm quarks replacing the two up quarks of the proton, thus quadrupling its mass. The discovery, presented at the ongoing Moriond conference, will help physicists better understand how the strong force binds protons, neutrons and other composite particles together. Quarks are fundamental building blocks of matter and come in six flavours: up, down, charm, strange, top and bottom. They usually combine in groups of twos and threes to form mesons and baryons, respectively. Unlike the stable proton, however, most of these mesons and baryons, which are collectively known as hadrons, are unstable and short-lived, making them a challenge to observe. Producing them requires smashing together high-energy particles in a machine such as the Large Hadron Collider (LHC). These unstable hadrons will quickly decay, but the more stable particles that are produced as a result of this decay can be detected and the properties of the original particle can therefore be deduced. Researchers have used this approach many times to find new hadrons, and the new particle just announced by the LHCb Collaboration brings the total number of hadrons discovered by LHC experiments up to 80. “This is the first new particle identified after the upgrades to the LHCb detector that were completed in 2023, and only the second time a baryon with two heavy quarks has been observed, the first having being observed by LHCb almost 10 years ago,” says LHCb Spokesperson Vincenzo Vagnoni. “The result will help theorists test models of quantum chromodynamics, the theory of the strong force that binds quarks into not only conventional baryons and mesons but also more exotic hadrons such as tetraquarks and pentaquarks.” In 2017, LHCb reported the discovery of a very similar particle, which consists of two charm quarks and one up quark. This up quark is the only difference between this particle and the new one, which has a down quark in its place. Despite the similarity, the new particle has a predicted lifetime that is up to six times shorter than its counterpart, due to complex quantum effects. This makes it even more challenging to observe. By analysing data from proton–proton collisions recorded by the LHCb detector during the third run of the LHC, the LHCb Collaboration observed the new baryon with a statistical significance of 7 sigma, well above the threshold of 5 sigma required to claim a discovery. “This major result is a fantastic example of how LHCb’s unique capabilities play a vital role in the success of the LHC,” says Mark Thomson, CERN Director-General. “It highlights how experimental upgrades at CERN directly lead to new discoveries, setting the stage for the transformative science we expect from the High-Luminosity LHC. These achievements are only possible thanks to the exceptional performance of CERN’s accelerator complex and the teams who make it all work and to the commitment of the scientists on the LHCb experiment.” Further information: LHCb presentation at Moriond is available here.

Why "CPT" is the Universe's most unbreakable symmetry

The combination of charge conjugation, parity, and time-reversal symmetry is known as CPT. And it must never be broken. Ever.
