In the <a href="https://home.cern/science/physics/standard-model">Standard Model of particle physics</a>, the Higgs boson’s mass is closely related to the strength of the particle’s interaction with itself. Comparing precise measurements of these two properties is a crucial means of testing the predictions of the Standard Model and helps search for physics beyond the predictions of this theory. In addition to probing its “self-interaction†strength, the researchers have also paid careful attention to the exact mass of the Higgs boson.</p>

After two successful data-collection runs, the detector is being upgraded to improve the precision of its physics measurements, many of which are the best in the world. There will therefore be five times more collisions every time proton bunches cross within the detector after LS2 and the LHCb collaboration plans on increasing the data-readout rate from 1 MHz to the LHC’s maximum interaction frequency of 40 MHz (or every 25 nanoseconds).</p>
<p>In addition to replacing nearly all of the electronics and data-acquisition systems to handle the enormous increase in data production, LHCb is replacing its tracking detectors with new ones, such as the scintillating-fibre tracker, or SciFi. It is the first time such a large tracker, with a small granularity and high spatial resolution, has been made using this technology. The SciFi will be placed behind the dipole magnet of LHCb.</p>
