Precision determination of the dpi<-->NN transition strength at threshold.
An unusual but effective way to determine at threshold the dpi<-->NN transition strength alpha is to exploit the hadronic ground-state broadening Gamma(1s) in pionic deuterium, accessible by x-ray spectroscopy. The broadening is dominated by the true absorption channel dpi(-)-->nn, which is related to s-wave pion production pp-->dpi(+) by charge symmetry and detailed balance. Using the exotic a...
متن کاملCoulomb resummation for bb̄ system near threshold and precision determination
Coulomb resummation for b ¯ b system near threshold and precision determination of α s and m b. Abstract We analyze sum rules for the Υ system with resummation of threshold effects on the basis of the nonrelativistic Coulomb approximation. We find for the pole mass of the bottom quark m b = 4.75 ± 0.04 GeV and for the strong coupling constant α s (M Z) = 0.118 ± 0.006. The origin of the contrad...
متن کاملStrength and precision of neurotransmission at mammalian presynaptic terminals
Classically, the basic concept of chemical synaptic transmission was established at the frog neuromuscular junction, and direct intracellular recordings from presynaptic terminals at the squid giant presynaptic terminal have further clarified principles of neurotransmitter release. More recently, whole-cell patch-camp recordings from the calyx of Held in rodent brainstem slices have extended th...
متن کاملThe Precision Determination of Invisible-Particle Masses at the LHC
We develop techniques to determine the mass scale of invisible particles pair-produced at hadron colliders. We employ the constrained mass variable m2C , which provides an event-by-event lower-bound to the mass scale given a mass difference. We complement this variable with a new variable m2C,UB which provides an additional upper bound to the mass scale, and demonstrate its utility with a reali...
متن کاملPrecision determination of Vub
We review how to determine |Vub| from inclusive semileptonic B decay using combined cuts on the leptonic and hadronic invariant masses to eliminate the b → c background. This leads to a determination of |Vub| with theoretical uncertainty at the 5–10% level. LBNL-49079, UCSD/PTH 01-22, UTPT-01-13 The magnitude of Vub determines the length of one of the side of the unitarity triangle and is there...
