Description
Flavour-changing neutral current decays such as c -> u l+ l– are highly suppressed in the Standard Model (SM), but may be enhanced by New Physics. For D0 -> μ+ μ–, the SM decay rate is dominated by long distance contributions but is still a few order of magnitudes below the current experimental limit. In decays such as D+ -> π+ μ+ μ–, measuring the differential branching ratio as a function of the μ+ μ– invariant mass is a sensitive probe for New Physics contributions. We present results of searches for rare charm decays with the 2011 LHCb data sample, corresponding to an integrated luminosity of 1.0 fb–1.
