Direct detection of an arrow of time

prof. dr hab. Ludwik Turko


Recent result of the BABAR collaboration concerning microscopic time-reversal non-invariance will be presented. Time reversal violation effects have been usually claimed through the registration of the CP (charge-parity) violation effects in kaons and B meson decay and then as the corollary from the CPT theorem. Recent BABAR study, published in October this year, of B meson decays allows for a direct observation of time-reversal non-invariance without relying on CPT symmetries. This important and fundamental result is based on the quantum entanglement of B0-antiB0 states resulting from the Upsilon Y(4s) meson decay.
