Precise measurement of the Λ0 and Λ¯0 masses and a test of CPT invariance
A precision measurement of the masses of the Λ0 and Λ¯0 hyperons is obtained from Gaussian fits to the invariant mass distributions for 20 138 Λ0’s and 18 309 Λ¯0’s. The Gaussians have standard deviations of 0.49 and 0.51 MeV/c2 for the Λ0 and Λ¯0, respectively. Systematic errors were reduced by cal...

Precise measurement of the Λ0 and Λ¯0 masses and a test of CPT invariance |
| abstract |
A precision measurement of the masses of the Λ0 and Λ¯0 hyperons is obtained from Gaussian fits to the invariant mass distributions for 20 138 Λ0’s and 18 309 Λ¯0’s. The Gaussians have standard deviations of 0.49 and 0.51 MeV/c2 for the Λ0 and Λ¯0, respectively. Systematic errors were reduced by calibrating the spectrometer with 60 000 exclusive events containing a KS0. We find MΛ=1115.678±0.006±0.006 MeV/c2 and MΛ¯=1115.690±0.008±0.006 MeV/c2. The Λ0-Λ¯0 mass difference testing CPT invariance is -0.012±0.010 MeV/c2. |

The Gaussians have standard deviations of 0.49 and 0.51 MeV/c2 for the Λ0 and Λ¯0, respectively. Systematic errors were reduced by calibrating the spectrometer with 60 000 exclusive events containing a KS0. We find MΛ=1115.678±0.006±0.006 MeV/c2 and MΛ¯=1115.690±0.008±0.006 MeV/c2. The Λ0-Λ¯0 mass difference testing CPT invariance is -0.012±0.010 MeV/c2.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">APS Digital Backfile Archive 1893-2003</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hartouni, E.
