Signatures of the Type-I 2HDM at the LHC

Rikard Enberg, William Klemm, Stefano Moretti +1

One of the simplest extensions of the Standard Model (SM) is the two-Higgs-doublet model (2HDM), which contains two neutral Higgs bosons, in addition to a 125 GeV one, and a charge…

Assessing the sensitivity of PINGU to effective dark matter-nucleon interactions

Anton Bäckström, Riccardo Catena, Carlos Pérez de los Heros

We calculate the sensitivity of next generation neutrino telescopes to the 28 (isoscalar and isovector) coupling constants defining the non-relativistic effective theory of (spin 1…

Electroweak production of multiple (pseudo)scalars in the 2HDM

Rikard Enberg, William Klemm, Stefano Moretti +1

The two-Higgs Doublet Model (2HDM) is the most minimal extension of the Standard Model (SM) containing extra Higgs doublet fields. Given the multiplicity of Higgs states in a 2HDM,…

Search for steady point-like sources in the astrophysical muon neutrino flux with 8 years of IceCube data

IceCube Collaboration, M. G. Aartsen, M. Ackermann +325

The IceCube Collaboration has observed a high-energy astrophysical neutrino flux and recently found evidence for neutrino emission from the blazar TXS 0506+056. These results open…

Next-to-leading-order predictions for single vector-like quark production at the LHC

Giacomo Cacciapaglia, Alexandra Carvalho, Aldo Deandrea +5

We propose simulation strategies for single production of third generation vector-like quarks at the LHC, implementing next-to-leading-order corrections in QCD and studying in deta…

$R_{D^{(*)}}$ motivated $S_{1}$ leptoquark scenarios: Impact of interference on the exclusion limits from LHC data

Tanumoy Mandal, Subhadip Mitra, Swapnil Raz

Motivated by the persistent anomalies in the semileptonic $B$ -meson decays, we investigate the competency of LHC data to constrain the $R_{D^{(*)}}$ -favoured parameter space in a c…

On the relationship between gauge dependence and IR divergences in the $ℏ$ -expansion of the effective potential

Andreas Ekstedt, Johan Löfgren

Perturbative calculations of the effective potential evaluated at a broken minimum, $V_{min}$ , are plagued by difficulties. It is hard to get a finite and gauge invariant…

Cosmological window onto the string axiverse and the supersymmetry breaking scale

Luca Visinelli, Sunny Vagnozzi

In the simplest picture, the masses of string axions populating the axiverse depend on two parameters: the supersymmetry breaking scale $M_{susy}$ and the action $S$ of the str…

Polarization observables in $e^{+} e^{-}$ annihilation to a baryon-antibaryon pair

Elisabetta Perotti, Göran Fäldt, Andrzej Kupść +2

Using the helicity formalism of Jacob and Wick we derive spin density matrices of baryon antibaryon pairs produced in $e^{+} e^{-}$ annihilation. We consider the production of pairs wit…

Towards solving the proton spin puzzle

Andreas Ekstedt, Hazhar Ghaderi, Gunnar Ingelman +1

The fact that the spins of the quarks in the proton, as measured in deep inelastic lepton scattering, only add up to about 30 $%$ of the spin of the proton is still not understood…

Dispersion relation for hadronic light-by-light scattering: pion pole

Martin Hoferichter, Bai-Long Hoid, Bastian Kubis +2

The pion-pole contribution to hadronic light-by-light scattering in the anomalous magnetic moment of the muon $(g - 2)_{μ}$ is fully determined by the doubly-virtual pion transition fo…

Nucleon parton distributions from hadronic quantum fluctuations

Andreas Ekstedt, Hazhar Ghaderi, Gunnar Ingelman +1

A physical model is presented for the non-perturbative parton distributions in the nucleon. This is based on quantum fluctuations of the nucleon into baryon-meson pairs convoluted…

Pion-pole contribution to hadronic light-by-light scattering in the anomalous magnetic moment of the muon

Martin Hoferichter, Bai-Long Hoid, Bastian Kubis +2

The $π^{0}$ pole constitutes the lowest-lying singularity of the hadronic light-by-light (HLbL) tensor, and thus provides the leading contribution in a dispersive approach to HLbL sc…

The relativistic chiral Lagrangian for decuplet and octet baryons at next-to-leading order

Måns Holmberg, Stefan Leupold

A complete and minimal relativistic Lagrangian is constructed at next-to-leading order for SU(3) chiral perturbation theory in the presence of baryon octet and baryon decuplet stat…
