Two-pion low-energy contribution to the muon with improved precision from analyticity and unitarity
B. Ananthanarayan, Irinel Caprini, Diganta Das +1
The two-pion contribution from low energies to the muon magnetic moment anomaly, although small, has a large relative uncertainty since in this region the experimental data on the…
Determination of the strong coupling from hadronic tau decays using renormalization group summed perturbation theory
Gauhar Abbas, B. Ananthanarayan, I. Caprini
We determine the strong coupling constant α_s from the τhadroni width using a renormalization group summed (RGS) expansion of the QCD Adler function. The main theoretical uncertain…
Invisible decays of the lightest Higgs boson in supersymmetric models
B. Ananthanarayan, Jayita Lahiri, P. N. Pandita +1
We consider supersymmetric models in which the lightest Higgs scalar can decay invisibly consistent with the constraints on the ~GeV state discovered at the CERN LHC. We consi…
Probing the indefinite CP nature of the Higgs Boson through decay distributions in the process
B. Ananthanarayan, Sumit K. Garg, Jayita Lahiri +1
The recently discovered scalar resonance at the LHC is now almost confirmed to be a Higgs Boson, whose CP properties are yet to be established. At the ILC with and without polarize…
Parametrization-free determination of the shape parameters for the pion electromagnetic form factor
B. Ananthanarayan, I. Caprini, Diganta Das +1
Recent data from high statistics experiments that have measured the modulus of the pion electromagnetic form factor from threshold to relatively high energies are used as input in…
