===== Parameters for Physics Studies in mu+mu- collisions   =====
Points shown in <color #ed1c24>**RED**</color> to be included into the Snowmass Summary plots/tables. Additional points (in black) are optional, but can be used to demonstrate performance in the presence of realistic beam background connditions. 
|COM Energy | <color #ed1c24>**125 GeV**</color> | 1.5 TeV | <color #ed1c24>**3 TeV**</color>  | 6 TeV  |  <color #ed1c24>**10 TeV**</color> | 14 TeV |  30 TeV |
|Total Luminosity (ab-1) |  <color #ed1c24>0.020 </color>|  0.25 |  <color #ed1c24>1.0</color> |  4.0  |  <color #ed1c24>10</color> | 10 | 10 |
<color #00a2e8>**Comments:**</color>\\
- Total luminosity is per interaction point and assumes 5 years of datataking at each energy. \\
- Higgs Factory 125 GeV luminosity projections are higher than those corresponding to the MAP design and assume improvements from recent advancements in technology and potentially a higher duty cicle. The projection assumes  narrow energy spread of the beam, which is beneficial for Higgs production and width measurements. \\
- Two detectors can be planned (except for 125 GeV), which will further increase luminosity by a factor of 2.\\
- Please contact us for configurations not included in the table or with any other questions.\\
<color #00a2e8>- Note that we are still finalizing parameters for the muon-ion collider studies.</color>
