Addendum to "On the consistency of MPS"

, 2013
The analogies between the Moving Particle Semi-implicit method (MPS) and Incompressible Smoothed Particle Hydrodynamics method (ISPH) are established in this note, as an extension of the MPS consistency analysis conducted in "Souto-Iglesias et al ...

Double-real contribution to the quark beam function at N3LO QCD

Journal of High Energy Physics, 2019
We compute the master integrals required for the calculation of the double-real emission contributions to the matching coefficients of 0-jettiness beam functions at nextto-next-to-next-to-leading order in perturbative QCD.

Integral of the double-emission eikonal function for a massive and a massless emitter at an arbitrary angle

Journal of High Energy Physics
We present an analytic calculation of the integrated double-emission eikonal function of a massive and a massless emitter whose momenta are at an arbitrary angle to each other.

Bottom-quark effects in Higgs production at intermediate transverse momentum

Journal of High Energy Physics, 2018
We provide a precise description of the Higgs boson transverse momentum distribution including top and bottom quark contributions, that is valid for transverse momenta in the range m b  ≲ p ⊥ ≲ m t , where m b and m t are the bottom and top quark masses.

Charge quantisation, monopoles and emergent symmetry in the Standard Model and its embeddings

Journal of High Energy Physics
This work studies the connection of the global properties of the SM gauge group to 1-form discrete symmetries, the possible non-Abelian embeddings of the SM group, and electric and magnetic charge quantisation.

Suppression of maximal linear gluon polarization in angular asymmetries

Journal of High Energy Physics, 2017
We perform a phenomenological analysis of the cos 2ϕ azimuthal asymmetry in virtual photon plus jet production induced by the linear polarization of gluons in unpolarized pA collisions.

Top quark FCNCs in extended Higgs sectors

European Physical Journal C: Particles and Fields, 2018
The large number of top quarks produced at the LHC and possible future hadron colliders allows to study rare decays of this particle. In many well motivated models of new physics, for example in non-minimal composite-Higgs models, the existence of scalar

Contributions from $${\Phi }_{B2}$$ ΦB2 to the B $${\rightarrow }$$ → PP decays within the QCD factorization

European Physical Journal C: Particles and Fields, 2019
With the potential for the improvements of measurement precision, the refinement of theoretical calculation on hadronic B weak decays is necessary. In this paper, we study the contributions of B mesonic distribution amplitude $${\Phi }_{B2}$$ ΦB2 within ...

muCool: a next step towards efficient muon beam compression

European Physical Journal C: Particles and Fields, 2019
A novel device to compress the phase space of a muon beam by a factor of $$10^{10}$$ 1010 with a $$10^{-3}$$ 10-3 efficiency is under development. A surface muon beam is stopped in a helium gas target consisting of several compression stages, wherein ...
