Confined and Deconfined Spinon Excitations in the Rectangular-lattice Quantum Antiferromagnet

Henrik Moodysson Rønnow, Bruce Normand, Ellen Fogh, Noore Elahi Shaik

Fractionalization remains one of the most fascinating manifestations of strong interactions in quantum many-body systems. In quantum magnetism, the existence of spinons-collective magnetic excitations that behave as quasiparticles with fractional quantum n ...

Extracting the speed of sound in quark-gluon plasma with ultrarelativistic lead-lead collisions at the LHC

Jan Steggemann, Konstantin Androsov, Anna Mascellani, Joanna Malgorzata Wanczyk

Ultrarelativistic nuclear collisions create a strongly interacting state of hot and dense quark-gluon matter that exhibits a remarkable collective flow behavior with minimal viscous dissipation. To gain deeper insights into its intrinsic nature and fundame ...

Measurements of KS0-KL0 asymmetries in the decays Λc+→ pKL,S0, pKL,S0 π+ π- and pKL,S0 π0

Yunxuan Song

Using e(+)e(-) annihilation data sets corresponding to an integrated luminosity of 4.5 fb(-1), collected with the BESIII detector at center-of-mass energies between 4.600 and 4.699 GeV, we report the first measurements of the absolute branching fractions B ...

Observation of WWγ Production and Search for Hγ Production in Proton-Proton Collisions at √s=13 TeV

Jan Steggemann, Konstantin Androsov, Anna Mascellani, Joanna Malgorzata Wanczyk

The observation of WWγ production in proton-proton collisions at a center-of-mass energy of 13 TeV with an integrated luminosity of 138 fb-1 is presented. The observed (expected) significance is 5.6 (5.1) standard deviations. Events are selected by requiri ...

Stochastic quantisation of Yang-Mills-Higgs in 3D

Martin Hairer

We define a state space and a Markov process associated to the stochastic quantisation equation of Yang-Mills-Higgs (YMH) theories. The state space S is a nonlinear metric space of distributions, elements of which can be used as initial conditions for the ...

Wigner kernels: Body-ordered equivariant machine learning without a basis

Michele Ceriotti, Sergey Pozdnyakov, Filippo Bigi

Machine-learning models based on a point-cloud representation of a physical object are ubiquitous in scientific applications and particularly well-suited to the atomic-scale description of molecules and materials. Among the many different approaches that h ...

Efficient co-upcycling of glycerol and CO2 into valuable products enabled by a bifunctional Ru-complex catalyst

Jiaqi Xu

Glycerol and CO2 are largely produced as by-products in modern industry. Herein, three Ru complexes bearing air- and water-stable NHC-nitrogen-nitrogen ligands are designed as bifunctional catalysts to upcycle glycerol and CO2 simultaneously. Among them, R ...

Search for long-lived particles decaying to jets with displaced vertices in proton-proton collisions at root s=13 Te V

Jan Steggemann

A search is presented for long-lived particles produced in pairs in proton-proton collisions at the LHC operating at a center-of-mass energy of 13 TeV. The data were collected with the CMS detector during the period from 2015 through 2018, and correspond t ...
