Universal machine learning for the response of atomistic systems to external fields

Yaolong Zhang

Machine learned interatomic interaction potentials have enabled efficient and accurate molecular simulations of closed systems. However, external fields, which can greatly change the chemical structure and/or reactivity, have been seldom included in curren ...

Predicting molecular dipole moments by combining atomic partial charges and atomic dipoles

Michele Ceriotti, David Mark Wilkins, Max David Veit

The molecular dipole moment (mu) is a central quantity in chemistry. It is essential in predicting infrared and sum-frequency generation spectra as well as induction and long-range electrostatic interactions. Furthermore, it can be extracted directly-via t ...

Studying the different coupling regimes for a plasmonic particle in a plasmonic trap

Olivier Martin, Jeonghyeon Kim

Plasmonic antennas improve the stiffness and resolution of optical tweezers by producing a strong near-field. When the antenna traps metallic objects, the optically-resonant object affects the near-field trap, and this interaction should be examined to est ...

The bearable compositeness of leptons

Luca Vecchi

Partial compositeness as a theory of flavor in the lepton sector is assessed. We begin presenting the first systematic analysis of neutrino mass generation in this context, and identifying the distinctive mass textures. We then update the bounds from charg ...

Theta dependence in holographic QCD

We study the effects of the CP-breaking topological theta-term in the large N-c QCD model by Witten, Sakai and Sugimoto with N-f degenerate light flavors. We first compute the ground state energy density, the topological susceptibility and the masses of th ...

The Bayesian reconstruction of the in-medium heavy quark potential from lattice QCD and its stability

We report recent results of a non-perturbative determination of the static heavy-quark potential in quenched and dynamical lattice QCD at finite temperature. The real and imaginary part of this complex quantity are extracted from the spectral function of W ...

REVIEW OF PARTICLE PHYSICS Particle Data Group

Olivier Schneider, Varun Sharma, Pierre Vogel, Christophe Bauer, Greig Alan Cowan

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,283 new measurements from 899 Japers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, lepton ...

Higgs couplings in composite models

Francesco Riva, Riccardo Torre

We study Higgs couplings in the composite Higgs model based on the coset SO(5)/SO(4). We show that the couplings to gluons and photons are insensitive to the elementary-composite mixings and thus not affected by light fermionic resonances. Moreover, at lea ...

On Partial Compositeness and the CP asymmetry in charm decays

Riccardo Rattazzi, Duccio Pappadopulo, Luca Vecchi, Paolo Lodone, Boaz Keren Zur

Recently, the LHCb and CDF Collaborations reported the measure of an unexpectedly large direct CP asymmetry in D meson decays. In this paper we ask if new physics associated with Partial Compositeness could plausibly explain this result. We find that Compo ...
