Overview Introduction of Quarks Basic building pieces of nature Definition Scale Discovery of Quarks Theoretical confirmation Flavors and hues The contrast in the middle of protons and neutrons Summary

Slide 3

Basic Building Blocks of Nature What is the world made of? Empedocles initially ordered the basic components as flame, air, earth, and water. (c. 450 B.C.) By tradition there is shading, By tradition sweetness, By tradition severity, But as a general rule there are particles and space.  â â -Democritus (c. 400 B.C.) Is the iota crucial?

Slide 4

Basic Building Blocks of Nature The particle is incorrectly named. The Greek pull for the word iota, αï…ï„î¿î¼î¿î½ , implies "that which can\'t be divided." But iotas are produced using littler particles! The iota contains adversely charged particles, electrons, encompassing an emphatically charged center, the core. Be that as it may, even this core isn’t basic! It is comprised of two sorts of particles, protons and neutrons.

Slide 5

Basic Building Blocks of Nature So, are these protons and neutrons principal particles? Physicists have found that protons and neutrons are made out of considerably littler particles called quarks. After broad testing, most physicist trust that quarks are the littlest particles – they are not made of whatever else. Core Electrons

Slide 6

Quarks: Definition “Quarks are a basic matter particles that are constituents of neutrons and protons and other matter particles.” Name originates from James Joyce: “Three quarks for Muster Mark.” Finnegan’s Wake The names are not imperative. Enrico Fermi once said to his understudy, “Young man, in the event that I could recollect the names of these particles, I would have been a botanist!” Quarks are considered piece of the “Standard Model” of Physics.

Scale: Size of quarks

Slide 8

Scale: Size of Quarks Width of proton = 1 cm centimeter Width of quarks = not exactly the breadth of a hair Width of iota = more than the length of thirty football fields! Proton width Quark width

Slide 9

Discovery: Theory The proton and neutron were seen to have comparative mass. This persuaded that they were comprised of something that was just marginally distinctive. Murray Gell-Mann proposed (Nobel - 1969) the presence littler matter particles that had electrical charges that were a small amount of the charge of an electron. Quarks are never watched exclusively so at first they were viewed as scientific fiction.

Slide 10

Flavors and Colors A quark’s flavor and shading have nothing to do with taste or what it would seem that. Six flavors: Up (1968), Down (1968), Strange (1974), Charm (1974), Beauty (1977), Truth (1995) Three hues: Red , Green , Blue These sorts of names are what happen when researchers attempt to be artists.

Slide 11

P N d u d Difference in the middle of Protons and Neutrons Protons and neutrons comprise of three quarks. Proton = up + up + down Charge = 2/3 + 2/3 - 1/3= +1 Neutron = up + down + down Charge = 2/3 - 1/3 - 1/3= 0

Slide 12

Summary Quarks are a fundamental building piece of nature. Quarks are 100,000,000 times littler than an iota. Quarks come in 6 distinct flavors and 3 unique hues. Quarks make up a piece of the “standar
