Search for high-mass exclusive diphoton production with tagged protons in proton-proton collisions at √s=13 TeV

Matthias Finger, Qian Wang, Varun Sharma, Konstantin Androsov, Jan Steggemann, Ian Smith, Xin Chen, Rakesh Chawla, Michele De Palma, Matteo Galli

A search is presented for high-mass exclusive diphoton production via photon-photon fusion in proton-proton collisions at root s = 13 TeV in events where both protons survive the interaction. The analysis utilizes data corresponding to an integrated lumino ...

Amplitude analysis of the D+-> pi(-)pi(+)pi(+) decay and measurement of the pi(-)pi(+) S-wave amplitude

Lesya Shchutska, Olivier Schneider, Aurelio Bay, Guido Haefeli, Frédéric Blanc, Tatsuya Nakada, François Fleuret, John Martin Kolinski, Mingkui Wang, Chao Wang

An amplitude analysis of the D+-> (-)pi(+)pi(+) decay is performed with a sample corresponding to 1.5 fb(-1) of integrated luminosity of pp collisions at a centre-of-mass energy root s = 8 TeV collected by the LHCb detector in 2012. The sample contains app ...

Measurement of the inclusive and differential t(t)over-bar gamma cross sections in the dilepton channel and effective field theory interpretation in proton-proton collisions at root s=13 TeV

Matthias Finger, Varun Sharma, Olivier Martin, Ian Smith, Jean-François Carlin, Arvind Shah, Rakesh Chawla, Thomas Mountford, Chao Wang, João Miguel das Neves Duarte

The production cross section of a top quark pair in association with a photon is measured in proton-proton collisions in the decay channel with two oppositely charged leptons (e(+/-)mu(-/+), e(+)e(-), or mu(+)mu(-)). The measurement is performed using 138 ...

Canted antiferromagnetic phases in the candidate layered Weyl material EuMnSb2

Xiaoqiang Wang, Xiao Wang

EuMnSb2 is a candidate topological material which can be tuned towards a Weyl semimetal, but there are differing reports for its antiferromagnetic (AFM) phases. The coupling of bands dominated by pure Sb layers hosting topological fermions to Mn and Eu mag ...

Nonreciprocity in Uniform Time-Varying Materials Using Spatial Dispersion

Xiaoqiang Wang, Mohammad Sajjad Mirmoosa, Xiao Wang

Conventionally, nonreciprocity in time-varying systems is achieved by exploiting both temporal and spatial modulations. In this paper, we introduce a concept of magnetless bianisotropic time-modulated systems that support nonreciprocal wave propagation at ...

Temporal Modulation of Bianisotropic Metasurfaces for Unidirectional Wave Amplification

Xiaoqiang Wang, Mohammad Sajjad Mirmoosa, Xiao Wang

Nonreciprocity in time-modulated metasurfaces is normally achieved only when it is combined with with space modulation, using at least two time-varying elements located at different positions in space. In this talk, we present the idea of time-modulated bi ...

Nonreciprocity in Bianisotropic Systems with Uniform Time Modulation

Xiaoqiang Wang, Mohammad Sajjad Mirmoosa, Xiao Wang

Physical systems with material properties modulated in time provide versatile routes for designing magnetless nonreciprocal devices. Traditionally, nonreciprocity in such systems is achieved exploiting both temporal and spatial modulations, which inevitabl ...

Highly anisotropic interlayer magnetoresitance in ZrSiS nodal-line Dirac semimetal

Oleg Yazyev, Xiaoqiang Wang, Quansheng Wu, Shengnan Zhang

We instigate the angle-dependent magnetoresistance (AMR) of the layered nodal-line Dirac semimetal ZrSiS for the in-plane and out-of-plane current directions. This material has recently revealed an intriguing butterfly-shaped in-plane AMR whose origin is n ...

Three-Dimensional Electron Realm in VSe2 by Soft-X-Ray Photoelectron Spectroscopy: Origin of Charge-Density Waves

Helmuth Berger, Thorsten Schmitt, Xiaoqiang Wang, Vladimir N. Strocov

The resolution of angle-resolved photoelectron spectroscopy (ARPES) in three-dimensional (3D) momentum k is fundamentally limited by ill defined surface-perpendicular wave vector k(perpendicular to) associated with the finite photoelectron mean free path. ...
