Beautiful and charming chromodipole moments

چکیده
In the context of Standard Model effective field theory we derive direct and indirect bounds on chromodipole operators involving bottom charm quark. We find that experimental upper limit neutron electric dipole moment puts severe constraints imaginary parts Wilson coefficients both operators. The magnitudes are instead only weakly constrained by dijet searches Z-boson production in association with bottom-quark jets. Flavour physics does not provide meaningful bounds.

Penguin Amplitudes: Charming Contributions *
We briefly introduce the Wick-contraction parametrization of hadronic matrix elements and discuss some applications to B and K physics. In spite of the progresses in non-perturbative techniques, the computation of hadronic matrix elements is still an open problem, particularly when the final state contains more than one meson. In this case, methods based on Euclidean field theory, such as QCD s...
متن کاملCharming Penguins in B Decays
Full expressions of the B0 d → π+π− and B0 d → π0π0 amplitudes, given in terms of matrix elements of operators of the effective weak Hamiltonian, are used to study the dependence of the relevant branching ratios on the different contributions. The uncertainty in the extraction of the weak phase α from the measurement of the timedependent asymmetry in B0 d → π+π− decays is also analyzed. We find...

We discuss few selected topics related to the calculation of hadronic amplitudes relevant for two-body non-leptonic B decays. Introduction It is likely that most of the future results in B phenomenology, including the study of CP violation, will come from the measurements of two-body non-leptonic decays. The major theoretical problem in predicting the rates of these decays is the evaluation of ...
متن کاملCharming the Snake
Snake venoms are potent cocktails containing a diverse array of proteins that typically target neuromuscular junctions or the hemostatic system of the snake’s prey. Many of the venom proteins that target hemostasis adopt a C-type lectinlike fold and are therefore termed snaclecs (ie, snake venom C-type lectins). Despite the structural similarity to functional lectins, the snaclecs do not exhibi...
متن کاملCharming Exascale Power Problems
Power, energy and reliability present major challenges to HPC researchers in their endeavor to build larger machines. As we approach the exascale era, both hardware and software designers need to account for these challenges while optimizing performance. The Parallel Programming Laboratory (PPL) at the University of Illinois at Urbana-Champaign (UIUC) has been actively working on meeting these ...
