Resumen

We present a search for pair produced top squarks, the supersymmetric partners of the top quark, using the D0 detector at the Fermilab Tevatron p¯p collider. We consider a scenario in which the lighter of the two top squarks ˜t₁ decays with 100% branching fraction to a charm quark and the lightest neutralino ˜χ⁰ ₁ yielding a signal of two acollinear jets with missing transverse energy. We observe 3 events while we expect 3.5 α 1.2 events from the known standard model processes. We exclude at the 95% confidence level a significant region of the m_t₁- m_{χ₁ ⁰} parameter space. The highest m_t₁ value we exclude is 93GeV/c² with a corresponding m_{χ₁ ⁰} value of 8GeV/c².
