The charmonium-like exotic states Y(4230) and the less known Y(4320), produced in e+e− collisions, are sources of positive parity exotic hadrons in association with photons or pseudoscalar mesons. We analyze the radiative and pion decay channels in

From a study of the lineshape of the $X(3872)$, the LHCb collaboration measures a sizeable negative effective range. This cannot be reconciled with a shallow $D\bar{D}^*$ bound state hypothesis. Based on Weinberg's compositeness criterion, together w

It is well known that the analysis of a relativistic n-body problem invariant under the transformations of the Poincar? group and involving only one time has only been done for n = 1. For n > 1 one uses the second quantization formalism of field theo

Use of the Dirac equation for a single particle in an electromagnetic field has led to many successful predictions. For more than one particle, the approach is usually through quantum field theory. In this contribution, we follow the original Dirac a

An exact single-level resonance formula for the survival probability S(t) in the full time interval, that depends only on the resonance energy r and the decay width ?r and fulfils time-reversal invariance, is used to discuss the non-exponential contr

Atomic and molecular physicists have developed extensive and detailed approximate methods for dealing with the relativistic versions of the Hamiltonians appearing in their fields. Nuclear physicists were originally more concerned with non-relativisti

The essays in this book aim to map the nature and extent of the societal impacts of Big Science and the mechanisms that generate such effects, as well as highlight the complex realities that can be used as guidelines to fund Big Science facilities, a
