Subleading contributions in rare semileptonic B$^+ \to \pi^+ \ell^+ \ell^-$ decay
Particles and Nuclei International Conference, PANIC 2021, LisboaLisboa, Portugal, 5 Sep 2021 - 10 Sep 20212021-09-052021-09-10 Proceedings of Science / International School for Advanced Studies (PANIC2021), 158 () [10.22323/1.380.0158]  GO
In the Standard Model, the $b \to s$ and $b \to d$ flavor-changing neutral currents (FCNC) are induced by loop effects. Rare semileptonic $B$-meson decays originated by these currents are standard channels for testing the Standard Model precisely and in searching for possible physics beyond it. [...]

Heavy Neutrinos at Future Linear $e^+e^-$ Colliders
Particles and Nuclei International Conference, PANIC 2021, LisboaLisboa, Portugal, 5 Sep 2021 - 10 Sep 20212021-09-052021-09-10 Proceedings of Science / International School for Advanced Studies (PANIC2021), 269 () [10.22323/1.380.0269]  GO
With the Standard Model being unable to describe the observed baryon asymmetry or dark matter density in the universe, many models of New Physics introduce heavy neutrino species as a possible explanation for these effects. Dirac or Majorana neutrinos with masses above the electroweak scale could be produced at future linear e+e- colliders, such as the Compact LInear Collider (CLIC) or the International Linear Collider (ILC).

Search for sterile neutrinos in low-energy double-cascade events with the IceCube Neutrino Observatory: a first expected sensitivity
Particles and Nuclei International Conference, PANIC 2021, LisboaLisboa, Portugal, 5 Sep 2021 - 10 Sep 20212021-09-052021-09-10 Proceedings of Science / International School for Advanced Studies (PANIC2021), 299 () [10.22323/1.380.0299]  GO
Sterile neutrinos are a well motivated facet of the new physics landscape. From their role in the mechanism through which Standard Model (SM) neutrinos acquire mass, to their potential explanation of anomalies in oscillation experiments and even as Dark Matter candidates, these hypothetical particles are thought to play a central part in the near future of particle physics.

Probing QCD at the LHC: Role of the top Quark
Particle Physics at the Year of 150th Anniversary of the Mendeleev's Periodic Table of Chemical Elements : [Proceedings] - WORLD SCIENTIFIC, 2021. - ISBN 978-981-12-3390-6
19th Lomonosov Conference on Elementary Particle Physics, MoscowMoscow, Russian Federation, 22 Aug 2019 - 28 Aug 20192019-08-222019-08-28
WORLD SCIENTIFIC, 2068723 7 pp. () [10.1142/9789811233913_0042]  GO
Successful running of the LHC at collision energies of 5, 7, 8 and 13 TeV allowed for a wealth of precision tests of the quantum chromodynamics and for significant improvement of the exclusion limits on various exotic processes. Produced in proton-proton collisions at the LHC, the top quark, the most massive fundamental particle, plays important role in tests of self-consistency of the Standard Model and provides new insights into the structure of the proton.

Bimetallic M$_x$Ru$_{100−x}$ nanoparticles (M = Fe, Co) on supported ionic liquid phases (M$_x$Ru$_{100−x}$@SILP) as hydrogenation catalysts: Influence of M and M:Ru ratio on activity and selectivity
Seminar, GermanyGermany, Journal of catalysis 407, 141 - 148 () [10.1016/j.jcat.2022.01.030]  GO
Bimetallic iron-ruthenium and cobalt-ruthenium nanoparticles with systematic variations in the Fe:Ru and Co:Ru ratios are prepared following an organometallic approach and immobilized on an imidazolium-based supported ionic liquid phase (SILP). Resulting MxRu100-x@SILP materials are characterized by electron microscopy, X-ray diffraction and X-ray absorption spectroscopy, confirming the formation of small, well-dispersed and alloyed zero-valent bimetallic nanoparticles.

An exceptionally light axion: Strong CP and Dark Matter
[DESY 21-180; DESY-21-180; arXiv:2111.03149]
European Physical Society Conference on High Energy Physics 2021, EPS-HEP2021, OnlineOnline, Germany, 26 Jul 2021 - 30 Jul 20212021-07-262021-07-30 Proceedings of Science / International School for Advanced Studies 398, 6 () [10.22323/1.398.0177]  GO
We explore whether the axion which solves the strong CP problem can naturally be much lighter than the canonical QCD axion. The $Z_\mathcal{N}$ symmetry proposed by Hook, with $\mathcal{N}$ mirror and degenerate worlds coexisting in Nature and linked by the axion field, is considered and the associated phenomenology is studied in detail.

Impact of polarized e$^-$ and e$^+$ beams at a future Linear Collider and a Z-factory. Part II: Physics beyond the standard model
[DESY-10-243]
Workshop on Sources of Polarized Leptons and High Brightness Electron Beams, PESP2010, BonnBonn, Germany, 21 Sep 2010 - 24 Sep 20102010-09-212010-09-24 Journal of physics / Conference Series 298, 012001 () [10.1088/1742-6596/298/1/012001]  GO
Polarization of both beams at a future Linear Collider would be ideal for facing both expected and unforeseen challenges in searches for new physics: fixing the chirality of the couplings and enabling the higher precision for the polarization meas urement itself as well as for polarization-dependent observables, it provides a powerful tool for studying new physics at the future Linear Collider, such as discovering new particles, analyzing signals model-independently and resolving precisely the unde rlying model. Techniques and engineering designs for a polarized-positron source are well advanced. [...]
