Study of the decay asymmetry parameter and CP violation parameter in the Λc+ → Λπ+ decay

, 2006
Using data from the FOCUS (E831) experiment at Fermilab, we present a new measurement of the weak decay-asymmetry parameter αΛc in Λc+→Λπ+ decay. Comparing particle with antiparticle decays, we obtain the first measurement of the CP violation parameter A≡

Progress in computing inclusive B decay spectra. [PDF]

, 2006
We review the progress in the QCD calculation of inclusive decay spectra. It was recently shown that the inherent infrared finiteness of inclusive spectra extends beyond the level of logarithms.

On the Selection of Weight Decay Parameter for Faulty Networks [PDF]

IEEE Transactions on Neural Networks, 2014
The weight-decay technique is an effective approach to handle overfitting and weight fault. For fault-free networks, without an appropriate value of decay parameter, the trained network is either overfitted or underfitted.

Parameter study of decaying magnetohydrodynamic turbulence

Physical Review E, 2023
It is well known that helical magnetohydrodynamic (MHD) turbulence exhibits an inverse transfer of magnetic energy from small to large scales, which is related to the approximate conservation of magnetic helicity. Recently, several numerical investigations noticed the existence of an inverse energy transfer also in nonhelical MHD flows. We run a set of

Update of electroweak parameters fromZ decays [PDF]

Zeitschrift für Physik C Particles and Fields, 1993
Based on 520 000 fermion pairs accumulated during the first three years of data collection by the ALEPH detector at LEP, updated values of the resonance parameters of the Z are determined to be M Z =(91.187±0.009) GeV, Γ Z =(2.501±0.012) GeV, σ{had/0}=(41.60±0.27) nb, and R l=20.78±0.13.

Decay Functions and Offender Spatial Processes [PDF]

, 2011
Although it is now well established across diverse samples that the frequency of offending ‘decays’ as distance from the home/base increases, it remains unclear what form of decay function best characterises this relationship.
