The patterns can be used to map out the distribution of mass thereby more accurately defining cosmologically important properties like the masses of neutrinos tiny elementary particles prevalent throughout the cosmos.

ROCHESTER/STONY BROOK (US)# Scientists have announced the first definitive observation of the transformation of muon neutrinos to electron neutrinos#a type of neutrino oscillation that had never been observed.#
#In 1998 the discovery of neutrino oscillation in the atmospheric neutrinos by the Super-Kamiokande experiment led us to a new journey into the fascinating and mysterious world of neutrinos
The experiment shows that researchers can now accurately observe the type of neutrino oscillation that will need to be studied in detail in future experiments aiming to measure CP violation explains Steven Manly professor of physics at the University of Rochester and part of the collaboration.
whether or not it would be feasible to explore CP violation in neutrinos. CP violation has only been observed in another type of particle quarks (for
which Nobel prizes were awarded in 1980 and 2008) never in neutrinos. The observed type of neutrino oscillation is sensitive to CP violation
and the T2k experiment will try to observe this process in neutrinos over coming years.
It could be that the asymmetry between matter and antimatter lies with neutrinos which is why observing CP violation in neutrinos would be exciting Manly adds.#
#Our goal now is to push to better understand the errors in the measurements and continue to collect sufficient data to explore this possible CP violation.#
Manly explains that neutrinos are notoriously difficult to study and the oscillation that the researchers seek can be mimicked by other processes.
For that reason the University of Rochester group has focused on understanding these other processes to ensure that what is measured is really the neutrino oscillation they have sought.
The neutrino beam is monitored by a detector complex in Tokai and aimed at the gigantic Super-Kamiokande underground detector in Kamioka near the west coast of Japan 295 kilometers (185 miles) away from Tokai.
An analysis of the data from the Super-Kamiokande detector associated with the neutrino beam time from J-PARC reveals that there are more electron neutrinos (a total of 28 events) than would be expected (4. 6 events) without this new process.
The map even shows that the number of neutrino flavours permeating the cosmos will probably remain at three#had there been a fourth,
