Calculations of pseudoscalar decay constants of B, Bs, K and pi mesons with physical light quarks are presented. We use HISQ ensembles that include u,d,s and c sea quarks at three lattice spacings. HISQ is used for the ...

We calculate semileptonic form factors for the decays $B_c \to \eta_c \, l \nu$ and $B_c \to J/\psi \, l \nu$ over the entire $q^2$ range, using a highly improved lattice quark action for charm at several lattice spacings ...

As a toy model for QED in strong background fields, we consider the impact of back-reaction and loop effects on scattering processes in quantum optics. We show that neglecting back-reaction misses qualitative and quantitative ...

The resident microbial community, harboured by humans in sites such as the skin and gastrointestinal tract, is enormous, representing a candidate environmental factor affecting susceptibility to complex diseases, where ...

Benzodiazepines are a large class of commonly-prescribed drugs used to treat a variety of clinical disorders. They have been shown to produce ecological effects at environmental concentrations, making understanding their ...

Wedged in-between the dense urban grain of Baghdad, blast walls of t-shaped concrete have littered the streets and neighbourhoods since 2003, after the US led invasion. The idiosyncrasy of these walls lies in their ...
