Supersymmetry versus Precision Experiments Revisited
We study constraints on the Minimal Supersymmetric Standard Model from electroweak experiments. We find that the light sfermions always make the fit worse than the Standard Model, while the light chargino generally make the fit slightly better through the oblique corrections. The best overall fit to the precision measurements are found when the mass of lighter chargino is about 100 GeV and the ...
متن کاملSupersymmetry versus precision experiments revisited
We study constraints on the supersymmetric standard model from the updated electroweak precision measurements — the Z-pole experiments and the W -boson mass measurements. The supersymmetric-particle contributions to the universal gauge-bosonpropagator corrections are parametrized by the three oblique parameters SZ , TZ and mW . The oblique corrections, the Zqq and Zll vertex corrections, and th...
متن کاملRetention behaviors of different attachment systems: precious versus nonprecious, precision versus semi-precision.
The aims of this study were to investigate the retention force changes of different attachment systems after 10,000 insertion-separation cycles and the difference in retention force between precious and non-precious materials of the same attachment system. Four types of attachments (Ball, Rod, M3 stud, and AP-Piccolino), produced using both precious and non-precious metal alloys, were tested (n...
متن کاملLight Sgoldstino: Precision Measurements versus Collider Searches
We study sensitivity of low-energy experiments to the scale of supersymmetry breaking √ F in models with light sgoldstinos — superpartners of goldstino. The limits on √ F may be obtained from direct and indirect measurements of sgoldstino coupling to photons, leptons, mesons and nucleons. There are three sources of constraints: (i) astrophysics and cosmology; (ii) precision laboratory experimen...
متن کاملConfusion
Acetaminophen (paracetamol) plays a vital role in American health care, with in excess of 25 billion doses being used annually as a nonprescription medication. Over 200 million acetaminophen-containing prescriptions, usually in combination with an opioid, are dispensed annually. While acetaminophen is recognized as a safe and effective analgesic and antipyretic, it is also associated with signi...
