The Belle experiment was a particle physics experiment conducted by the Belle Collaboration, an international collaboration of more than 400 physicists and engineers, at the High Energy Accelerator Research Organisation (KEK) in Tsukuba, Ibaraki Prefecture, Japan.
Christmas is an annual festival commemorating the birth of Jesus Christ,Martindale, Cyril Charles.
The Christmas season, also called the festive season, or the holiday season (mainly in the U.S. and Canada; often simply called the holidays),, is an annually recurring period recognized in many Western and Western-influenced countries that is generally considered to run from late November to early January.
Christmas Eve is the evening or entire day before Christmas Day, the festival commemorating the birth of Jesus.
Christmas traditions vary from country to country.
Exotic hadrons are subatomic particles composed of quarks and gluons, but which do not have the same quark content as ordinary hadrons: exotic baryons differ from the three-quark (qqq) content of ordinary baryons, and exotic mesons differ from the quark-antiquark (q) content of ordinary mesons.
Non-quark model mesons include.
, known as KEK, is a Japanese organization whose purpose is to operate the largest particle physics laboratory in Japan, situated in Tsukuba, Ibaraki prefecture.
The LHCb (standing for "Large Hadron Collider beauty") experiment is one of seven particle physics detector experiments collecting data at the Large Hadron Collider at CERN.
In particle physics, mesons are hadronic subatomic particles composed of one quark and one antiquark, bound together by strong interactions.
New Year is the time or day at which a new calendar year begins and the calendar's year count increments by one.
New Year's Day, also called simply New Year's or New Year, is observed on January 1, the first day of the year on the modern Gregorian calendar as well as the Julian calendar.
In the Gregorian calendar, New Year's Eve (also known as Old Year's Day or Saint Sylvester's Day in many countries), the last day of the year, is on 31 December which is the seventh day of Christmastide.
In quantum mechanics, a parity transformation (also called parity inversion) is the flip in the sign of one spatial coordinate.
In particle physics, a resonance is the peak located around a certain energy found in differential cross sections of scattering experiments.
In statistical hypothesis testing, a result has statistical significance when it is very unlikely to have occurred given the null hypothesis.
A tetraquark, in particle physics, is an exotic meson composed of four valence quarks.
In quantum mechanics, the total angular momentum quantum number parameterises the total angular momentum of a given particle, by combining its orbital angular momentum and its intrinsic angular momentum (i.e., its spin).
The X(3872) is an exotic meson candidate with a mass of 3871.68 MeV/c2 which does not fit into the quark model because of its quantum numbers.
The Y(4140) particle is an electrically neutral exotic hadron candidate that is about 4.4 times heavier than the proton.
The Zc(3900) is a hadron, a type of subatomic particle made of quarks, believed to be the first tetraquark that has been observed experimentally.
2018 has been designated as the third International Year of the Reef by the International Coral Reef Initiative.
2019 (MMXIX) will be a common year starting on Tuesday of the Gregorian calendar, the 2019th year of the Common Era (CE) and Anno Domini (AD) designations, the 19th year of the 3rd millennium, the 19th year of the 21st century, and the 10th and last year of the 2010s decade.
