Discrepancy between experimental and theoretical β-decay rates resolved from first principles [PDF]

Nature Physics, 2019
The dominant decay mode of atomic nuclei is beta decay (β-decay), a process that changes a neutron into a proton (and vice versa). This decay offers a window to physics beyond the standard model, and is at the heart of microphysical processes in stellar ...

On the interior geometry of a typical black hole microstate

Journal of High Energy Physics, 2019
We argue that the region behind the horizon of a one-sided black hole can be probed by an analogue of the double-trace deformation protocol of Gao-Jafferis-Wall.

Electronic properties and applications of MXenes: a theoretical review [PDF]

, 2017
The recent chemical exfoliation of layered MAX phase compounds to novel two-dimensional transition metal carbides and nitrides, the so-called MXenes, has brought a new opportunity to materials science and technology.

Flavour anomalies after the R K ∗ measurement

Journal of High Energy Physics, 2017
The LHCb measurement of the μ/e ratio R K ∗ indicates a deficit with respect to the Standard Model prediction, supporting earlier hints of lepton universality violation observed in the R K ratio.

Quantum corrections to finite radius holography and holographic entanglement entropy

Journal of High Energy Physics, 2020
We calculate quantum corrections to holographic entanglement entropy in the proposed duality between T T ¯ $$ T\overline{T} $$ -deformed holographic 2D CFTs and gravity in AdS3 with a finite cutoff.

A conjectural generating function for numbers of curves on surfaces

, 1997
I give a conjectural generating function for the numbers of $\delta$-nodal curves in a linear system of dimension $\delta$ on an algebraic surface. It reproduces the results of Vainsencher for the case $\delta\le 6$ and Kleiman-Piene for the case $\delta\

Theoretical Review of B-physics [PDF]

, 1996
Weak decays and mixing of B-hadrons play a special role in our understanding of the physics of the Standard Model and beyond. The measured amplitudes, however, result from a complicated interplay of weak and strong interaction effects.

Data‐driven performance metrics for neural network learning

International Journal of Adaptive Control and Signal Processing, EarlyView., 2023
Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

LEvEL: Low-Energy Neutrino Experiment at the LHC

Journal of High Energy Physics, 2021
We propose the operation of LEvEL, the Low-Energy Neutrino Experiment at the LHC, a neutrino detector near the Large Hadron Collider Beam Dump. Such a detector is capable of exploring an intense, low-energy neutrino flux and can measure neutrino cross ...

On the Twisted $N=2$ Superconformal Structure in $2d$ Gravity Coupled to Matter

, 1993
It is shown that the two dimensional gravity, described either in the conformal gauge (the Liouville theory) or in the light cone gauge, when coupled to matter possesses an infinite number of twisted $N=2$ superconformal symmetries.
