Hilbert series, the Higgs mechanism, and HEFT

Brian Quinn Henning

We expand Hilbert series technologies in effective field theory for the inclusion of massive particles, enabling, among other things, the enumeration of operator bases for non-linearly realized gauge theories. We find that the Higgs mechanism is manifest a ...

Boson star normal modes

Hung-Hsu Chan

Boson stars are gravitationally bound objects that arise in ultralight dark matter models and form in the centers of galactic halos or axion miniclusters. We systematically study the excitations of a boson star, taking into account the mixing between posit ...

Measurement of the mass dependence of the transverse momentum of lepton pairs in Drell-Yan production in proton-proton collisions at √s=13TeV

Jan Steggemann, Konstantin Androsov

\The double differential cross sections of the Drell-Yan lepton pair (l(+)l(-), dielectron or dimuon) production are measured as functions of the invariant mass m(ll), transverse momentum p(T)(ll), and phi(eta). The phi(eta) observable, derived from angu ...

Convergent momentum-space OPE and bootstrap equations in conformal field theory

Marc Gillioz

General principles of quantum field theory imply that there exists an operator product expansion (OPE) for Wightman functions in Minkowski momentum space that converges for arbitrary kinematics. This convergence is guaranteed to hold in the sense of a dist ...

L'événement proxémique : étude des relations de circulation entre piétons aux heures de pointe à Delhi, Los Angeles, Paris et Tokyo

Lucas François Tiphine

In a context of traffic networks saturation related to urbanisation acceleration, this research is aimed at contributing to the scientific debate on this issue by building a model to describe dynamic pedestriansâ physical distances regulation behaviours ...
