Search for long-lived heavy neutrinos in the decays of B mesons produced in proton-proton collisions at √s=13 TeV

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

A search for long-lived heavy neutrinos (N) in the decays of B mesons produced in proton-proton collisions at root s = 13 TeV is presented. The data sample corresponds to an integrated luminosity of 41.6 fb(-1) collected in 2018 by the CMS experiment at th ...

Tetraquarks at large M and large N

Riccardo Rattazzi, Filippo Nardi, Stefan Stelzl, Majid Ekhterachian, Héloïse Allaman

We study tetraquarks in large N QCD with heavy quarks, in the domain where non-relativistic quantum mechanics offers an adequate approximation. Within the regime of validity of the Born-Oppenheimer approximation, we systematically study and explicitly cons ...

Single monkey-saddle singularity of a Fermi surface and its instabilities

Christopher Marc Mudry

Fermi surfaces can undergo sharp transitions under smooth changes of parameters. Such transitions can have a topological character, as is the case when a higher-order singularity, one that requires cubic or higher-order terms to describe the electronic dis ...

Direct determination of the topological thermal conductance via local power measurement

Sofia Konyzheva

Thermal conductance measurements are sensitive to both charge and chargeless energy flow and are an essential measurement technique in condensed-matter physics. For two-dimensional topological insulators, the determination of thermal Hall (transverse) cond ...

Ab initio theory of magnetism in two-dimensional 1T-TaS2

Oleg Yazyev, Diego José Pasquier

We investigate, using a first-principles density functional methodology, the nature of magnetism in monolayer 1T phase of tantalum disulfide (1T-TaS2). Magnetism in the insulating phase of TaS2 is a longstanding puzzle and has led to a variety of theoretic ...

Heavy impurity transport in tokamaks subject to plasma rotation, NTV and the influence of saturated ideal MHD perturbations

Jonathan Graves, Cristian Sommariva, Eduardo José Lascas Neto

Strongly peaked tungsten accumulation is a common feature of high performance plasma scenarios in JET with the ITER-like wall, particularly during MHD activity induced by m/n = 1/1 continuous modes. This study investigates the effect of 1/1 long living int ...

Results on quiescent and post-disruption runaway electrons studies at Frascati Tokamak Upgrade: RE mitigation via solid deuterium pellets and anomalous Doppler instability

Stefano Coda, Basil Duval

Results from the last FTU campaigns on RE mitigation strategies for quiescent and post-disruption RE beams are presented. We provide experimental evidence that for some RE quiescent scenarios D-2 solid pellets achieve complete RE suppression capability, ma ...
