of particles for 50 years. here s our science correspondent pallab ghosh. scientists explain how the universe works using the theories of physics. but those ideas could be about to change. a particle accelerator just outside chicago has made a measurement that could change physics forever. researchers here have discovered that the mass of a subatomic particle called a w boson is not what it should be. and in the world of physics, that s a huge deal. the world could look very different. it could mean that the standard model as we know it is wrong, or it needs to be modified in some important way. it is also possible that there are other fundamental particles out there waiting to be discovered, and our colleagues around the world will have a lot of fun discovering them. the standard model is one of the most important theories in physics. and in the journal nature, researchers say this might be
The standard model of particle physics has stood the test of time for decades, but now a new measurement of a particle called the W boson could indicate a chink in its armour
to contact the russian state. and finally, i want to tell you about a new discovery which is being described as the first step in a big shift in our understanding of the universe. scientists at fermilab just outside chicago have found that the mass of a particle is not what the main theory of sub atomic physics states it should be. the result has been described as shocking by the researchers because the theory has successfully predicted the behaviour and properties of particles for 50 years. here s our science correspondent pallab ghosh. scientists explain how the universe works using the theories of physics. but those ideas could be about to change. a particle acceleratorjust outside chicago has made a measurement that could change physics forever. researchers here have discovered that the mass of a subatomic particle called a w boson
