With three rotational degrees of freedom of spatial Dreibeins and an appropriate Lagrangian we describe electromagnetic phenomena. Stable solitonic excitations we compare with the lightest fundamental electric charges, electrons and positrons. Two Goldstone bosons we relate to the properties of photons. These particles are characterised by three topological quantum numbers, corresponding to...

Antiproton-nucleus annihilation at rest is a process that is not well understood, despite substantial previous experimental and theoretical work on its different aspects. One of the main reasons for its complexity are final-state interactions (FSIs), i.e. the interactions between the primary mesons produced and the residual nucleus. A model that accounts for all the observed effects is still...

In the context of direct detection experiments, we consider the scenario where dark matter and Standard Model particles interact through two dark vector mediators, one light and one heavy with respect to the momentum transfer in the experiment. From such phenomenology interference effects arise at the level of scattering amplitudes, leading to novel shape features in the differential recoil...

In the past decades, numerous experiments have emerged to unveil the nature of dark matter (DM), one of the most discussed open questions in modern particle physics. Direct detection experiments aim to measure scattering of relic DM particles off a target material. Cryogenic solid-state detectors equipped with transition edge sensors have proved to compete very well in the quest for...

The aim of this project is to study the production of dielectrons with the ALICE experiment at the LHC.
Go to contribution page
The production of low-mass dielectrons is one of the most promising tools for the understanding of the chiral symmetry restoration and of the thermodynamical properties of the Quark-Gluon plasma (QGP), created in ultra-relativistic heavy-ion collisions. Since such pairs do not interact... -

High-precision jet mass measurements for processes involving boosted top quark pair production relevant for the determination of the top quark mass eventually require the systematic inclusion of electroweak and finite lifetime effects. For boosted top quark initiated inclusive jets we apply an electroweak Soft-Collinear-Effective-Theory (SCET) framework that allows for a coherent resummation...

Abstract: An inclusive search for long-lived exotic particles decaying to a pair of muons is presented. The search uses a data set collected by the CMS experiment at the LHC in proton-proton collisions at 13 TeV in 2016 and 2018 and corresponding to an integrated luminosity of 97.6 fb−1. The experimental signature is a pair of oppositely charged muons originating from a common secondary vertex...

I will review recent development of Monte Carlo event generators, and in particualr their core, parton shower, component. Several improvements on the accuracy of these algorithms, and their relation to and use in analytic resummation, have been developed and start to impact the design of phenomenological models as well as pave the way to the inclusion of electroweak and beyond the Standard...

Mr Jan Luedtke (University of Vienna)
Recently the Fermilab g-2 experiment has confirmed the long standing discrepancy between experimental measurement and Standard Model prediction of the muon's anomalous magnetic moment. This makes it timely to improve also the Standard Model calculation both in precision and robustness. In this talk, I will review recent progress in this direction with particular emphasis on the dispersive...

Despite intense efforts to understand its nature, the dark sector proves elusive. Rising tensions in observational data with Λ-CDM add to long-standing problems that clearly indicate that the present standard model/GR picture of our universe is incomplete.

We consider a dark Sp(4) gauge theory with $N_f=2$ fermions in the pseudo-real fundamental representation and construct the chiral low-energy effective theory. We determine the flavor multiplet structure and the chiral Lagrangian with the inclusion of the Wess-Zumino-Witten term for (non-)degenerate flavors. We provide implications when coupling to the Standard Model with a dark U(1) sector...

Coherent neutrino-nucleus scattering (CEvNS) is a promising new tool in the toolbox of electroweak precision measurements at low q-transfer. It will enable precise measurements of standard model (SM) physics but also the search for new physics beyond the SM.
The NUCLEUS experiment aims for the first fully coherent CEvNS detection at a new experimental site, the Very Near Site (VNS), between...
