The Multi-Channel Algebraic-Scattering (MCAS) method was developed in 2003 for the analysis of low-energy nuclear spectra and of resonant scattering. It continues to be used effectively for nuclear-structure studies. The MCAS approach allows the construction of the nucleon-core-nucleus model Hamiltonian which can be defined in detail (coupling to the collective modes, rotational or...

We present our most recent results regarding Near-BPS Skyrmions and argue that they provide an improved description of nucleons and nuclei. For some years now, the Skyrme Model and extensions have been considered natural candidates for a low-energy effective theory of QCD, a point of view supported by results coming from $1/N$ expansion and holographic QCD. This framework leads to an...

In 2003 Witten showed that the leading order of scattering amplitudes in the maximally supersymmetric gauge theory (MSYM) in four dimensions can be computed using a string-like formulation. Amplitudes are correlation functions computed on a punctured Riemann sphere. For many years this phenomenon was thought to be special to MSYM. In 2013, an explosion of string-like formulations were...

A careful analysis of $B\to K^*\mu^+\mu^-$ observables should consider the long-distance effects of the resonances in the short-distance dominated region. Here, we take into account the narrow
resonance effects in the nonresonance region when calculating the differential decay rate and the forward-backward asymmetry in this decay. In doing so, we use a Breit-
Wigner model for the resonances...

We use the colour dipole formalism to compute the rate for diffractive phi meson production using a holographic AdS/QCD wavefunction for the phi. We use a dipole cross-section with parameters fitted to the most recent and very precise 2015 HERA data on the proton's structure function. We compare our predictions on diffractive phi production to the data collected at the HERA collider and find...
