Abstract In this study, we demonstrate the potential of the NA64 experiment at CERN SPS to search for New Physics processes involving $$e\rightarrow \mu $$ e → μ transitions after the collision of 100 GeV electrons with target nuclei. A new Dark S

Abstract The inclusion of an additional U(1) gauge L μ − L τ symmetry would release the tension between the measured and the predicted value of the anomalous muon magnetic moment: this paradigm assumes the existence of a new, light Z′ vector bo

Sensitivity potential to a light flavor-changing scalar boson with DUNE and NA64 $$\mu $$ μ

Autor: B. Radics, L. Molina-Bueno, L. Fields, H. Sieber, P. Crivelli

Publikováno v: European Physical Journal C: Particles and Fields, Vol 83, Iss 9, Pp 1-7 (2023)

Abstract In this work, we report on the sensitivity potential of complementary muon-on-target experiments to new physics using a scalar boson benchmark model associated with charged lepton flavor violation. The NA64 $$\mu $$ μ experiment at CERN use

Highly conserved shifts in ubiquitin-proteasome system (UPS) activity drive mitochondrial remodeling during quiescence

Autor: Sibiao Yue, Lei Wang, George N. DeMartino, FangZhou Zhao, Yi Liu, Matthew H. Sieber

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-14 (2022)

Dynamic regulation of cellular proteostasis is linked to the metabolic state of quiescent cells in vivo. Here, the authors show, in multiple organisms, that shifts in the ubiquitin-proteome system are coupled to mitochondrial metabolic changes and su

Abstract We report the results of a search for a new vector boson ( $$ A'$$ A ′ ) decaying into two dark matter particles $$\chi _1 \chi _2$$ χ 1 χ 2 of different mass. The heavier $$\chi _2$$ χ 2 particle subsequently decays to $$\chi _1$$ χ 1

Abstract Recently, the ATOMKI experiment has reported new evidence for the excess of $$e^+e^-$$ e + e - events with a mass $$\sim $$ ∼ 17 MeV in the nuclear transitions of $$^4$$ 4 He, that they previously observed in measurements with $$^8$$ 8 Be.
