58. Search for high-mass non-resonant signals at CMS

Tobias Pook (Rheinisch-Westfaelische Tech. Hoch. (DE))

5/10/16, 2:00 PM

parallel talk

We present a summary of searches for new physics with non-resonant high mass signatures.
The talk focuses on W' and extra dimension models in mono lepton, dijet and multi particle final states using 2015 CMS data at $\sqrt{s}=13\,\mathrm{TeV}$.

90. Search for quark contact interactions and extra spatial dimensions with dijet angular distributions in proton proton collisions at 13 TeV

parallel talk

A search for quark contact interactions and extra spatial dimensions in dijet angular distributions in proton proton collisions at 13 TeV is presented. The data was collected by CMS detector at the CERN LHC and corresponds to an integrated luminosity of 2.6 fb-1. The measured distributions are found to be in good agreement with predictions from perturbative QCD that include electroweak...

129. Soft-Wall Light Dilatons

Don Bunk (Hamilton College)

parallel talk

We present holographic Randall-Sundrum like models of spontaneously broken conformal symmetry that realize a light dilaton and suppressed cosmological constant from condensates. A ''soft-wall'' realization of the RS geometry is generic in such cases, where the IR brane plays a lesser role as a cutoff for large curvature effects, and low energy observables such as the spectrum of states are...

143. 125 GeV Higgs boson mass from 5D gauge-Higgs unification

Prof. Nobuchika Okada (University of Alabama)

5/10/16, 2:45 PM

parallel talk

In the context of a simple gauge-Higgs unification (GHU) scenario based on the gauge group SU(3)×U(1)′ in a 5-dimensional flat space-time, we investigate a possibility to reproduce the observed Higgs boson mass of around 125 GeV. We introduce bulk fermion multiplets with a bulk mass and a (half) periodic boundary condition. In our analysis, we adopt a low energy effective theoretical approach...

54. Warped Seesaw is Physically Inverted

Mr Sungwoo Hong (University of Maryland)

5/10/16, 3:00 PM

parallel talk

Warped extra dimensions can address both the Planck-weak and flavor hierarchies of the Standard
Model (SM). In this paper we discuss the SM neutrino mass generation in a scenario in which a SM
singlet bulk fermion — coupled to the Higgs and the lepton doublet near the IR brane — is given
a Majorana mass of order the Planck scale on the UV brane. Despite the resemblance to a type I
seesaw...

119. Signals for heavy singlet neutrinos in natural warped seesaw and beyond

Peizhi Du (University of Maryland College Park)

parallel talk

Recently, it was shown that a canonical implementation of the type I seesaw mechanism in a warped extra dimensional framework is in reality a natural realization of ``inverse" seesaw, i.e., the SM neutrino mass is dominantly generated by exchange of pseudo-Dirac weak-scale SM singlet neutrinos. We study signals from production of these heavy singlet neutrinos at the LHC, using the...
