Anti Hadrons
Anti hadrons are made from the opposite quarks as their Hadron counterparts, for example a proton is made from the quark combination uud and an antiproton is made from the combination ūūd̄
We can see that a π+ and a π- are particle and antiparticle of each other.
| Anti Proton | Charge | Baryon Number (B) | Strangeness | Anti | Charge | Baryon Number (B) | Strangeness | |
|---|---|---|---|---|---|---|---|---|
| ū | -⅔ | -⅓ | 0 | d̄ | +⅓ | -⅓ | 0 | |
| ū | -⅔ | -⅓ | 0 | ū | -⅔ | -⅓ | 0 | |
| d̄ | +⅓ | -⅓ | 0 | d̄ | +⅓ | -⅓ | 0 | |
| p̄̄ | -1 | -1 | 0 | n̄ | 0 | -1 | 0 |
You need to know all the quark combination shown on this page as they may ask you to recite any of them.
