Displaced Higgs production in type III seesaw
Orlovskaya T.V.
et al.
Jul 14, 2010
We point out that the type III seesaw mechanism introducing fermion tripletspredicts peculiar Higgs boson signatures of displaced vertices with two b jetsand one or two charged particles which can be cleanly identified. In asupersymmetric theory, the scalar partner of the fermion triplet contains aneutral dark matter candidate which is almost degenerate with its chargedcomponents. A Higgs boson can be produced together with such a dark mattertriplet in the cascade decay chain of a strongly produced squark or gluino.When the next lightest supersymmetric particle (NLSP) is bino/wino-like, thereappears a Higgs boson associated with two charged tracks of a charged leptonand a heavy charged scalar at a displacement larger than about 1 mm. Thecorresponding production cross-section is about 0.5 fb for the squark/gluinomass of 1 TeV. In the case of the stau NLSP, it decays mainly to a Higgs bosonand a heavy charged scalar whose decay length is larger than 0.1 mm for thestau NLSP mixing with the left-handed stau smaller than 0.3. As this processcan have a large cascade production $\sim 2$ pb for the squark/gluino mass$\sim 1$ TeV, one may be able to probe it at the early stage of the LHCexperiment.

Aspects of Berry phase in QFT
Marie Kim Wium-Andersen
et al.
Jan 19, 2017
When continuous parameters in a QFT are varied adiabatically, quantum statestypically undergo mixing---a phenomenon characterized by the Berry phase. Weinitiate a systematic analysis of the Berry phase in QFT using standard quantummechanics methods. We show that a non-trivial Berry phase appears in manyfamiliar QFTs. We study a variety of examples including free electromagnetismwith a theta angle, and certain supersymmetric QFTs in two and four spacetimedimensions. We also argue that a large class of QFTs with rich Berry propertiesis provided by CFTs with non-trivial conformal manifolds. Using theoperator-state correspondence we demonstrate in this case that the Berryconnection is equivalent to the connection on the conformal manifold derivedpreviously in conformal perturbation theory. In the special case of chiralprimary states in 2d N=(2,2) and 4d N=2 SCFTs the Berry phase is governed bythe tt* equations. We present a technically useful rederivation of theseequations using quantum mechanics methods.

Entropy currents from holography in hydrodynamics with charge
Grzegorz Plewa
et al.
Apr 24, 2013
The holographic interpretation of the hydrodynamic entropy current isdeveloped for the case of hydrodynamics with a conserved charge. This iscarried out within a framework developed in earlier work, which showed how toassociate entropy currents with horizons in the dual geometry. The entropycurrent defined by the event horizon in the dual bulk geometry is calculated.It is also shown that to second order in the gradient expansion the dualgeometry possesses a unique Weyl-invariant apparent horizon which also definesan admissable entropy current. At first order both currents coincide with theresult obtained on the basis of a purely hydrodynamic analysis.

Di-Higgs signatures from R-parity violating supersymmetry as the origin of neutrino mass
Marie Kim Wium-Andersen
et al.
Apr 11, 2016
Motivated by the naturalness and neutrino mass generation, we study abilinear R-parity violating supersymmetric scenario with a light Higgsino-likelightest supersymmetric particle (LSP). We observe that the LSP dominantlydecays to $\nu h$ in a large part of the parameter space, and thus study thepair production of electroweakinos followed by the decays $\tilde\chi^\pm_1\to\tilde\chi^0_1 W^{\pm*}$ and $\tilde\chi^0_1\to \nu h$. This leads to aninteresting signature of Higgs boson pair production associated withsignificantly large missing transverse energy which is grossly distinct fromthe di-Higgs production in the Standard Model. We investigate the perspectiveof probing such signatures by performing a realistic detector level simulationof both the signal and corresponding backgrounds for the high-luminosity highenergy phase of the Large Hadron Collider (LHC). We also advocate someobservables based on kinematical features to provide an excellent handle tosuppress the backgrounds.

Signals of the electroweak phase transition at colliders and gravitational wave observatories
Mikael Chala
et al.
Feb 6, 2018
If the electroweak phase transition (EWPT) is of strongly first order due tohigher dimensional operators, the scale of new physics generating them is atthe TeV scale or below. In this case the effective-field theory (EFT)neglecting operators of dimension higher than six may overlook terms that arerelevant for the EWPT analysis. In this article we study the EWPT in the EFT todimension eight. We estimate the reach of the future gravitational waveobservatory LISA for probing the region in which the EWPT is strongly firstorder and compare it with the capabilities of the Higgs measurements viadouble-Higgs production at current and future colliders. We also matchdifferent UV models to the previously mentioned dimension-eight EFT anddemonstrate that, from the top-down point of view, the double-Higgs productionis not the best signal to explore these scenarios.
