"Hints of unexpected behaviour by a sub-atomic particle called the beauty quark could expose cracks in the foundations of this decades-old theory.
The findings emerged from data collected by researchers working at the Large Hadron Collider (LHC). It's a giant machine built in a 27km-long circular tunnel underneath the French-Swiss border. It smashes together beams of proton particles to probe the limits of physics as we know it.
The mystery behaviour by the beauty quark may be the result of an as-yet undiscovered sub-atomic particle that is exerting a force.
But the physicists stress that more analysis and data is needed to confirm the results."

"Hints of unexpected behaviour"

Sounds familiar.
It would have been bigger than finding the Higgs boson and marked the beginning of a new era in particle physics. But new data have squashed the hope that the hints of a new particle detected by the Large Hadron Collider (LHC) would solidify with time. Instead, the intriguing data ‘bump’ — first reported in December — turns out to be nothing more than a statistical fluctuation.

Statistical fluctuations in quantum states? Sounds more like The Deep Science State is hiding the data that can be used to travel through the Space-Time continuum and worm-holes to other universes

LHCb has studied a number of other such ratios comparing decays with different leptons in beauty particle decays (see RK, RK*0, R(D*), R(J/ψ) and RpK). These results revealed hints of deviations from lepton universality, none of which was statistically significant enough to constitute evidence of new physics on their own. However, according to theorists who study possible extensions of the Standard Model, these deviations combined suggest an interesting and coherent pattern. The previous measurement of RK used the LHCb Run 1 and the first part of Run 2 data set. The experimental method applied in today’s analysis is essentially identical but the analysis profits from additional data collected in 2017 and 2018. Measurements like RK apply a so-called blind analysis, in which the physicists analysing the data do not know the result until the analysis method is finalised and frozen, following an extended review within the collaboration.
Preprint paper.
The Standard Model of particle physics currently provides our best description of fundamental particles and their interactions. The theory predicts that the different charged leptons, the electron, muon and tau, have identical electroweak interaction strengths. Previous measurements have shown a wide range of particle decays are consistent with this principle of lepton universality. This article presents evidence for the breaking of lepton universality in beauty-quark decays, with a significance of 3.1 standard deviations, based on proton-proton collision data collected with the LHCb detector at CERN’s Large Hadron Collider. The measurements are of processes in which a beauty meson transforms into a strange meson with the emission of either an electron and a positron, or a muon and an antimuon. If confirmed by future measurements, this violation of lepton universality would imply physics beyond the Standard Model, such as a new fundamental interaction between quarks and leptons.

Hello there :) The universe, which we know and love, exists because the fundamental particles interact. These interactions include attractive and repulsive forces, decay, and annihilation.
With that said I must confess.

Ten years after the Higgs, physicists face the nightmare of finding nothing else
Then came a long hangover. Before the 27-kilometer-long ring-shaped LHC started to take data in 2010, physicists fretted that it might produce the Higgs and nothing else, leaving no clue to what lies beyond the standard model. So far, that nightmare scenario is coming true. “It’s a bit disappointing,” allows Barry Barish, a physicist at the California Institute of Technology. “I thought we would discover supersymmetry,” the leading extension of the standard model.
