First minimum bias physics results at LHCb

Understand

We report on the first measurements of the LHCb experiment, as obtained from $pp$ collisions at $\sqrt{s} = 0.9$ TeV and 7 TeV recorded using a minimum bias trigger.

• In particular measurements of the absolute $K^0_S$ production cross section at $\sqrt{s} = 0.9$ TeV and of the $\bar{\Lambda}/\Lambda$ ratio both at $\sqrt{s} = 0.9$ TeV and 7 TeV are discussed and preliminary results are presented.
