Long-Distance Signal Propagation in AC-LGAD

Casey Bishop, Ayan Das, Jane Ding +14

We investigate the signal propagation in AC-LGAD (aka RSD), which are LGAD with a common N+ layer and segmented AC-coupled readout contacts, by measuring response to IR laser TCT o…

Time-dependent analysis of $B^{0} \to K_{S}^{0} π^{-} π^{+} γ$ decays and studies of the $K^{+} π^{-} π^{+}$ system in $B^{+} \to K^{+} π^{-} π^{+} γ$ decays

P. del Amo Sanchez, others

We measure the time-dependent $C P$ asymmetry in the radiative-penguin decay $B^{0} \to K_{S}^{0} π^{-} π^{+} γ$ , using a sample of $471$ million $Υ(4S) \to B{\kern 0.18em\overline{\kern…

Search for Long-Lived Particles in $e^{+} e^{-}$ Collisions

J. P. Lees, others

We present a search for a neutral, long-lived particle $L$ that is produced in $e^{+} e^{-}$ collisions and decays at a significant distance from the $e^{+} e^{-}$ interaction point into var…

Measurement of $A_{c}$ with Charmed Mesons at SLD

The SLD Collaboration, K. Abe

We present a direct measurement of the parity-violation parameter $A_{c}$ in the coupling of the $Z^{0}$ to $c$ -quarks with the SLD detector. The measurement is based on a sample of 53…

Observation of Target Electron Momentum Effects in Single-Arm Møller Polarimetry

M. Swartz, H. R. Band, F. J. Decker +11

In 1992, L.G. Levchuk noted that the asymmetries measured in Møller scattering polarimeters could be significantly affected by the intrinsic momenta of the target electrons. This e…
