B-meson

Study of B-meson decay could help discover a new exotic particle

The Large Hadron Collider is being from a long time to study the rare particles decays and discover new particles. From 2009, LHC has been operated for thousands of experiments or mainly collisions and it has yielded many results such a discovery of Higgs Boson. Today, we know that the standard model scientists proposed to unify three fundamental forces of nature is not enough to explain the dark mysteries of physics. Though, standard model explains many theories and facts and gives accurate results. But, it doesn’t explain gravity and greatest mystery called “dark matter”.

When LHC was first started, many theorists assumed that particles predicted by an elegant extension to the standard model — supersymmetry — would reveal themselves as soon as colliders could reach a high enough energy. But, till now no supersymmetric particles been discovered and thus proved as a disappointment for scientists.

Still, they have not given up on supersymmetric particles and now they are thinking out of the box and ruling out simpler version of the theories. Now, rather than rely on conjuring new particles, many are hoping to observe their effects indirectly, prying open tiny cracks in the standard model by exploring a handful of findings that don’t quite fit predictions. One interesting topic is B-meson decay which is very rare. Physicists make precise measurements of how B mesons decay into known particles. They search for tiny discrepancies that would reveal the influence of hypothetical heavy particles.

Many discrepancies are discovered and none of them are are giving any clue. But collectively they are letting us see the big picture. Each anomaly hints at the existence of the same exotic new particle. The particle is not yet known but most probably it include a heavier type of Z boson — a Z?— or a “leptoquark”. Leptoquarks are particles that carry information between quarks and leptons of a given generation. It allow quarks and leptons to interact. They are color-triplet bosons that carry both lepton and baryon numbers.

If the particle really exists, it could be a fundamental particle that communicate in higher dimensions. The LHC will be upgraded to study the anomalies.  And by 2025 , they will able to increase the intensity of collisions. And truth will be unraveled over the mysteries behind B-meson decay.
