QuestionAnswer
HOW DO YOU PRODUCE W BOSONS ... PROTON AND ANTIPROTON COLLIDE.
IN BETA DECAY THE W BOSON MEETS THE ... NEUTRINO AND ANTINEUTRINO AND CHANGES THEM INTO BETA – PARTICLE (AN ELECTRON) OR A POSITRON(BETA+).
IF NO NEUTRINO OR ANTINEUTRINO PRESENT IN BETA DECAY THE W- BOSON ... DECAYS INTO B- PARTICLE AND ANTINEUTRINO.
THE W= BOSON DECAYS INTO... A POSITRON AND NEUTRINO. IF NO ANTI/NUETRINO PRESENT.
SOMETIMES A PROTON IN PROTON RICH NUCLEUS CHANGES INTO NEUTRON DUE TO.... INTERACTION THROUGH WEAK INTERACTION WITH INNER SHELL ELECTRON FROM OUTSIDE NUCLEUS.
W + BOSON CHANGES WHTA INTO WHT ... THE ELECTRON INTO NEUTRINO.
WHEN PROTON AND ELECTRON COLLIDE AT HIGH SPEEDS/PRODUCED.. ELECTRON INTO NUETRINO.
AND ALSO WHEN A W- BOSON EXCHANGE FORM THE ELECTRON TO THE PROTON.
COSMIC RAYS ARE... HIGHER ENERGY PARTICLE THAT TRAVEL THROUGH SPACE FORM STARS INCLUDING SUN.
WHEN COSMIC RAY ENTERS EARTH ATMOSPHERE IT CREATE... NEW SHORT LIVED PARTICLE AND ANTIPARTICLES AND PHOTONS.
MOST SCIENTIST THOUGHT THAT WHEN COSMIC RAYS WHERE... DISCOVERED THEY WERE FORM TERRESTRIAL RADIOACTIVE SOURCES. THEORY DISPROVED WHEN PHYSICIST VICTOR HESS FOUND THE IONISING AFFECTS OF RAYS WAS GREATER THAN 500M THAN GROUND LEVEL.
MOST COSMIC RAYS WHERE FAST MOVING/OR... PROTONS OR SMALL NUCLEI. THEY COLLIDE WITH GAS ATOMS IN ATMOSPHERE.
BECAUSE COSMIC RAYS COLLIDE WITH GAS ATOMS IN ATM IT CREATS... SHOWER OF PARTICLES AND ANTIPARTICLES THAT CAN BE DETECTED AT GROUND LEVEL.
BY USING CLOUD CHAMBERS AND OTHER DETECTORS WHAT TYPES OF SHORT LIVED PARTICLES AND ANTIPARTICLES DISCOVERED ...MUON – HEAVY ELECTRON (SYMBOL MU) A NEG CHANGED PARTICLE WITH REST MASS OVER 200 TIMES THE REST MASS OF ELECTRON. PION OR (PI MESON) PARTICLE THAT CAN BE POS CHARGE OR NEG OR NEUTRAL HAS REST MASS GREATER TAN MUSON BUT LESS THAN PROTON.KAON (K MESON) K – CAN BE POS NEG OR NEUTRAL HAS REST MASS GREATER THAN PION BUT LESS THAN A PROTON.
WHT IS A KAON ... A K MESON CAN BE POS NEG OR NEUTRAL .HAS REST MASS GREATER THAN PION BUT LESS THAN A PROTON
WHT IS A PION ... A PI MESON CAN BE POS CHARGE OR NEG OR NEUTRAL HAS REST MASS GREATER TAN MUSON BUT LESS THAN PROTON.
WHT IS MUON... HEAVY ELECTRON (SYMBOL MU) A NEG CHANGED PARTICLE WITH REST MASS OVER 200 TIMES THE REST MASS OF ELECTRON.
HIDEKEI YAKAWA PREDICTED THE EXISTENCE OF.... EXCHANGE PARTICLES FOR THE STRONG NUCLEAR FORCE BETWEEN NUCLEONS.
CARL ANDERSON DISCOVERED THAT A MUON PARTICLE WAS.... A HEAVY ELECTRON BUT NOT CLASSED AS A MESON.
IT DECAYS THROUGH WEAK INTERACTION. YAKAWA PREDICTIONS WAS CORRECT.
WHT INTERACTION DOES A MUON DECAY BY ... WEAK INTERACTION.
A SHORT SPIRAL TRACK IS A, PI POSITIVE MESON IS CREATED WHEN .... AN ANTIPROTON FROM THE BOTTOM EDGE ANNIHILATES A PROTONS. THE PI MESON DECAYS INTO ANTIMUON THAT SPIRAL'S AND DECAYS INTO POSITRON.
SHORT LIVED PARTICLES DISCOVERED CALLED.... K MESONS OR KAONS.
KAON ARE LIKE... PI MESONS PRODUCED THROUGH STRONG INTERACTION .WHEN PROTONS MOVING AT HIGH SPEED CRASH INTO NUCLEI AND THEY DECAY TRAVEL FAR BEYOND NUCLEUS BEFORE THEY DECAY.
KAON THEY DECAY THROUGH A... WEAK INTERACTION- EVEN THROUGH CREATED THROUGH STRONG INTERACTION.
KAONS THEIR DECAY CONSIST OF... PI MESONS – SO CALLED STRANGE PARTICLES.
PARTICLES KAON, PI MESON , MUON, CAN BE CREATED BY ... ACCELERATORS
WHT HAPS IN ACCEELRATORS ... PROTONS COLLIDE HEAD ON WITH OTHER PROTONS AT HIGH SPEED. THEIR KINETIC ENERGY OF PROTONS IS CONVERTED INTO MASS 0- IN CREATION OF NEW PARTICLES.
WHEN PROTONS COLLIDE HEAD ON IN ACCELERATOR THE KIN ENERGY CONVERTED INTO ... MASS 0- IN CREATION OF NEW PARTICLES.
K MESONS DECAY INTO... PI MESON, MUON AND ANTINEUTRINOS AND ANTIMUONS AND NEUTRINOS.
CHARGED PI MESONS DECAY INTO ... MUONS ANTINEUTRINOS , OR ANTIMUONS AND NEUTRINOS,
THE PI^0 MESON DECAYS INTO... HIGH ENERGY PHOTONS.
MUONS AND ANTIMUONS DECAY INTO ... ELECTRON AND ANTINEUTRINOS OR POSITRONS AND NEUTRINOS.
THE DECAYS ALWAYS OBEYS ... CONSERVATION LAWS FOR ENERGY AND CHARGE AND MOMENTUM.
