Antarctica’s Anomalies That Don’t Fit the Standard Model

Previous research has shown how a shower of particles is created by an avalanche of collisions caused by the high energy cosmic particles that meet the Earth and do not pass right through being stuck in one something else. The team of researchers at Penn State University are studying this process by tracking down and reporting particles over Antarctica due to the possibility that a high energy particle makes it all the way through, becoming a particle that does not yet exist in the Standard Model. In order to detect these particles researchers started a project called Antarctic Impulsive Transient Antenna (ANITA) which has tool to a high-altitude balloon hovering over Antarctica with a sensor attached.

The ANITA collaboration has managed to detect with their senor only to unusual particle events, εcr≈0.6 EeV cosmic ray showers emerging from the Earth with exit angles of 27 and 35, respectively, one back  in 2006, and one in 2014 proving the theory that a high-energy particle can somehow  get through without creating a particle shower. In 2006 the detection was not taken seriously due to the equipment problems or some other unknown obstacles. Not even the second one was considered so important but it sure caused more concern.

Extremely High Energy Northern Track neutrinos of the IceCube Neutrino Observatory is coming with new efforts to find evidence and report a type of particle from the two anomalies that will be challenging for the Standard Model. The new project is called IceCube and had sensors buried in Antarctica which gave them the new proofs that they needed. These sensors kept constantly detecting particle events. The report showed three events with unexplained properties arising the question, whether the anomalies hint at the possibility of particles beyond the Standard Model.
