Monodromy Charge in D7-brane Inflation

Understand

In axion monodromy inflation, traversing $N$ axion periods corresponds to discharging $N$ units of a quantized charge.

• In certain models with moving D7-branes, such as Higgs-otic inflation, this monodromy charge is D3-brane charge induced on the D7-branes.
• The stress-energy of the induced charge affects the internal space, changing the inflaton potential and potentially limiting the field range.
• We compute the backreaction of induced D3-brane charge in Higgs-otic inflation.
