Fundamental purgative is described by the so - shout Standard Model . It is one of the finest creations of humans , allow elaborate predictions of mote cathartic and improving our understanding of the universe like never before . Despite all this , it is limited . We know that it does n’t admit gravity , for deterrent example . So while , on the one hand , it is one of physics ' greatest pecker , on the other researchers are trying to obtain way to violate it . And one group might have done just that .
In a composition upload onarXiv , Professor Derek Fox from Penn State University and fellow worker described two anomalous observation from theAntarctic Impulsive Transient Antenna(ANITA ) experiment . According to the paper , these signal could not have been made by any particle within the Standard Model .
ANITA studies ultra - high muscularity cosmic neutrino . Neutrinos are particles with no electrical charge and a tiny mass . They can easily move through a planet unscathed . If you oblige up your thumb , about 100 billion neutrinos will pass through your thumbnail every second base .
Neutrinos can interact with issue once in a while . The energies of these exceptional cosmic ones are so in high spirits that they can turn into massive particles . One particular change was have a bun in the oven for certain tau neutrinos ( which is one of their types or “ flavors ” ) . They can plow into tau leptons , which is a wakeless adaptation of the standard electrons . The Standard Model has a very specific prediction for this change , but the recent observations do n’t equal . The angles of the particles detected by ANITA were much steeper than if it was a tau lepton . It must have been something else .
The team look at other potential nominee and nothing we have ever meet matched what they see in the datum . In the report , they suggest this could be an example of a supersymmetric mote akin to the tau lepton . Supersymmetryis a yet - to - be - proven theory that assigns to every cognise molecule a familiar to excuse some intrinsical difference we see in particle physics but are unmanageable to explain using the Big Bang Theory .
So is the Standard Model unfeignedly break in ? We ca n’t be sure just yet . The newspaper has been submitted to the diary Physics Review D , and it will be certainly picked apart in the peer - review process by many other groups around the world .
Even if it does n’t pan out , there are many other unusual person currently being investigate that point at physics beyond the Standard Model . The fundamental possibility might outlast this cogitation , but the moment we truly fall in it is incur closer and nigher every day .
