Abstract

Searches for scalar top, scalar bottom and degenerate scalar quarks have been performed with data collected with the ALEPH detector at LEP. The data sample consists of 57 pb^-1 taken at √s = 181-184 GeV. No evidence for scalar top, scalar bottom or degenerate scalar quarks was found in the channels t̃ → cx, t̃ → bℓṽ, b̃ → bx, and q̃ → qx. From the channel t̃ → cx a limit of 74 GeV/c₂ has been set on the scalar top quark mass, independent of the mixing angle. This limit assumes a mass difference between the t̃ and the x in the range 10-40 GeV/c₂. From the channel t̃ → bℓṽ the mixing-angle-independent scalar top limit is 82 GeV/c₂, assuming m_t̃ - m_ṽ > 10 GeV/c₂. From the channel b̃ → bx, a limit of 79 GeV/c₂ has been set on the mass of the supersymmetric partner of the left-handed state of the bottom quark. This limit is valid for m_b̃-m_x > 10 GeV/c₂. From the channel q̃ → qx a limit of 87 GeV/c₂ has been set on the mass of supersymmetric partners of light quarks assuming five degenerate flavours and the production of both "left-handed" and "right-handed" squarks. This limit is valid for mq̃-mx > 5 GeV/c₂.

N2 - Searches for scalar top, scalar bottom and degenerate scalar quarks have been performed with data collected with the ALEPH detector at LEP. The data sample consists of 57 pb-1 taken at √s = 181-184 GeV. No evidence for scalar top, scalar bottom or degenerate scalar quarks was found in the channels t̃ → cx, t̃ → bℓṽ, b̃ → bx, and q̃ → qx. From the channel t̃ → cx a limit of 74 GeV/c2 has been set on the scalar top quark mass, independent of the mixing angle. This limit assumes a mass difference between the t̃ and the x in the range 10-40 GeV/c2. From the channel t̃ → bℓṽ the mixing-angle-independent scalar top limit is 82 GeV/c2, assuming mt̃ - mṽ > 10 GeV/c2. From the channel b̃ → bx, a limit of 79 GeV/c2 has been set on the mass of the supersymmetric partner of the left-handed state of the bottom quark. This limit is valid for mb̃-mx > 10 GeV/c2. From the channel q̃ → qx a limit of 87 GeV/c2 has been set on the mass of supersymmetric partners of light quarks assuming five degenerate flavours and the production of both "left-handed" and "right-handed" squarks. This limit is valid for mq̃-mx > 5 GeV/c2.
