Enhanced molecular yield from a cryogenic buffer gas beam source via excited state chemistry [PDF]
New Journal of Physics, 2020 We use narrow-band laser excitation of Yb atoms to substantially enhance the brightness of a cold beam of YbOH, a polyatomic molecule with high sensitivity to physics beyond the standard model (BSM).

Moments of inertia by summation [PDF]
Revista Brasileira de Ensino de Física, 2023 This study delves into moment of inertia in rigid body mechanics, a crucial concept in physics. While it’s traditionally taught through integration, we propose an alternative method using discrete mass segments.

Flavor anomalies meet the LHC [PDF]
EPJ Web of Conferences, 2023 Currently there are several discrepancies between the standard model (SM) prediction and experimental value in the flavor observables, e.g. RD* , BR(B̄ → D+K−), RK(*) and muon anomalous magnetic moment.

Feasibility study of tau-lepton anomalous magnetic moment measurements with ultra-peripheral collisions at the LHC [PDF]
EPJ Web of Conferences, 2022 Precision measurements of the anomalous electromagnetic moment of leptons (al) may serve as one of the most promising directions in the search for new physics beyond the Standard Model.

Perspectives on electric dipole moments of atoms and molecules [PDF]
EPJ Web of Conferences, 2023 Searches for a permanent electric dipole moment (EDM) of a fundamental particle started with the key idea by Ramsey and Purcell of exploitation of discrete symmetries, such as parity, more than seven decades ago.

Boosted Tau Lepton as a Microscope and Macroscope
Advances in High Energy Physics, 2022 Anomalies from the LHCb lepton flavour universality and Fermilab muon anomalous magnetic moment show tantalizing hints of possible new physics from the lepton sectors.

Random matrix theory and moments of moments of $L$-functions [PDF]
Random Matrices: Theory and Appl. 12(3):2350002, 2023, 2022 We give an analytic proof of the asymptotic behaviour of the moments of moments of the characteristic polynomials of random symplectic and orthogonal matrices. We therefore obtain alternate, integral expressions for the leading order coefficients previously found by Assiotis, Bailey and Keating. We also discuss the conjectures of Bailey and Keating for

Enhancing searches for resonances with machine learning and moment decomposition
Journal of High Energy Physics, 2021 A key challenge in searches for resonant new physics is that classifiers trained to enhance potential signals must not induce localized structures. Such structures could result in a false signal when the background is estimated from data using sideband ...

Precision experiments with muons and neutrons
Comptes Rendus. Physique, 2020 The precision experiments with muons and neutrons are described. The topics selected cover the anomalies of the muon $g_{\mu }-2$ and the neutron lifetime, and searches for charged lepton flavour violation CLFV of ${\mu ^{-} \rightarrow e ...

European Physical Journal C: Particles and Fields, 2022 In this paper, using the Bestest Little Higgs Model (BLHM) we calculate at the one-loop level the contributions to the Anomalous Magnetic Dipole Moment (AMDM) and Anomalous Weak Magnetic Dipole Moment (AWMDM) of the tau-lepton. The implications from this
