33. Constraining new physics with Borexino Phase-II spectral data

Joao Paulo Pinheiro (Universitat de Barcelona)

BSM

We present a detailed analysis of the spectral data of Borexino Phase II, with
the aim of exploiting its full potential to constrain scenarios beyond the Standard Model. In
particular, we quantify the constraints imposed on neutrino magnetic moments, neutrino
non-standard interactions, and several simplified models with light scalar, pseudoscalar
or vector mediators. Our analysis shows...

53. Detecting Nanometer-Scale New Forces with Coherent Neutron Scattering

BSM

Significant effort has been devoted to searching for new fundamental forces of nature. At short length scales (below approximately 10 nm), the strongest experimental constraints come from neutron scattering from individual nuclei in gases. The leading experiments at longer length scales instead measure forces between macroscopic test masses. We propose a hybrid of these two approaches:...

135. Constraining light dark Z with low-energy experiments

Dr Eduardo Peinado Rodriguez (Instituto de Fisica UNAM, Mexico)

BSM

In this talk, we will present a study on the effects of the dark Z model in current and future low-energy parity-violating experiments. In particular, we will give the constraints from electroweak pole observables, CEvNS, BaBar, and the future sensitivity for SoLID. We will also present a re-analysis of other existing or upcoming low-energy experiments, such as E158, Qweak, P2, MOLLER, and...

BSM

For a class of macroscopic dark matter models, inelastic scattering of dark matter off a nucleus can generate electromagnetic signatures with GeV-scale energy. The IceCube detector, with its kilometer-scale size, is ideal for directly detecting such inelastic scattering. Based on the slow particle trigger for the DeepCore detector, we perform a detailed signal and background simulation to...

171. Searching for Dark Matter Annihilation with IceCube and P-ONE

Stephan Meighen-Berger

08/05/2023, 15:15

BSM

We present a new search for weakly interacting massive particles utilizing neutrino telescopes. We consider galactic and extra-galactic dark matter and analyze ten years of public IceCube data, setting stringent bounds on massive dark matter annihilation. In addition, we make predictions for P-ONE, a new neutrino telescope in the Pacific Ocean, showing that its sensitivity may even exceed...

80. Earth-Catalyzing Detection of Magnetic Inelastic Dark Matter

Graham Kribs

08/05/2023, 15:30

BSM

Inelastic dark matter with moderate splittings, $\mathcal{O}(\mathrm{f}\mathrm{e}\mathrm{w}\mathrm{t}\mathrm{o}150)$ keV, can upscatter to an excited state in the Earth, with the excited state subsequently decaying, leaving a distinctive monoenergetic photon signal in large underground detectors. I'll show that proposed large volume gaseous detectors (CYGNUS) will have excellent sensitivity to this signal. I'll...

244. Repurposing Precision SM Measurements to Constraint New Physics

Sagar Airen

BSM

We show how precision SM measurements can be repurposed to constraint certain types of new physics (NP) without invoking SMEFT. Motivated by highly precise measurement of W mass by the CDF collaboration, we demonstrate our proposal for the specific case of W mass data. W boson gives lepton + MET final state, which makes it special because it cannot be reconstructed completely. Any NP, which...
