Answer 1

Building blocks of hadrons

Question 2

What is a hadron?

Answer 2

Particle made up of quarks

Question 3

What are the two types of hadrons?

Answer 3

baryons and mesons

up quark u
charmed quark c
top quark t

down quark d
strange quark s
bottom quark b

Question 7

-1/3e

Question 8

Answer 9

top quark

Question 10

What is the lightest positive quark?

Answer 10

up quark

Question 11

What is the lightest negative quark?

Answer 11

down quark

Question 12

What is the heaviest negative quark?

Answer 12

botton quark

Question 13

How do we denote an antiquark?

Answer 13

quark symbol with a bar above it

Question 14

What is the property of a strange quark?

Answer 14

strangeness

Question 15

Why do we not know the precise mass of each quark?

Answer 15

As it is not possible to get a quark on its own (always comes with an antipartner) - meson

Question 16

What is this called?

Answer 16

quark confinement

Question 17

What is a baryon?

Answer 17

A type of a hadron, which contains 3 quarks.

Question 18

Example of baryon?

Answer 18

proton

Question 19

What do antiquarks have compared to quarks?remember the anti strange quark

Answer 19

Same mass, opposite charge , opposite baryon number (and if anti strange then opposite strangeness number.)
