Polarised antibranes from Smarr relations

We study the backreaction of smeared and localised anti m2-branes placed at the tip of the cglp background. to this end we derive a smarr relation for backreacted antibranes at zero and finite temperature. for extremal antibranes we show that if smeared they cannot have regular horizons, whereas localised m2-branes can potentially be regular when polarised into m5-branes, in agreement with the probe result of klebanov and pufu. we further discuss antibranes at finite temperature and argue that localised antibrane solutions with regular horizons are not excluded.
