Minimal Seesaw Model with a Discrete Heavy-Neutrino Exchange Symmetry
Thomas Rink, Kai Schmitz, Tsutomu T. Yanagida
We present a Froggatt-Nielsen flavor model that yields a minimal realization of the type-I seesaw mechanism. This seesaw model is minimal for three reasons: (i) It features only tw…
Augury of Darkness: The Low-Mass Dark Z' Portal
Alexandre Alves, Giorgio Arcadi, Yann Mambrini +2
Dirac fermion dark matter models with heavy mediators are subject to stringent constraints from spin-independent direct searches and from LHC bounds, cornering them to…
Minima of the Scalar Potential in the Type II Seesaw Model: From Local to Global
Xun-Jie Xu
The Type II seesaw model requires that its scalar doublet and triplet get specific patterns of VEVs and $\langleΔ\rangle\propto(0,0,1)^{T…
R-parity as a residual gauge symmetry : probing a theory of cosmological dark matter
Alexandre Alves, Giorgio Arcadi, P. V. Dong +3
We present a non-supersymmetric scenario in which the R-parity symmetry arises as a result of spontaneous gauge symmetry breaking, leading to a viable Dira…
Testing Higgs Coupling Precision and New Physics Scales at Lepton Colliders
Shao-Feng Ge, Hong-Jian He, Rui-Qing Xiao
The next-generation lepton colliders, such as CEPC, FCC-ee, and ILC will make precision measurement of the Higgs boson properties. We first extract the Higgs coupling precision fro…
Unification and Local Baryon Number
Pavel Fileviez Perez, Sebastian Ohmer
We investigate the possibility to find an ultraviolet completion of the simple extensions of the Standard Model where baryon number is a local symmetry. In the context of such theo…
Coherent Neutrino-Nucleus Scattering and new Neutrino Interactions
Manfred Lindner, Werner Rodejohann, Xun-Jie Xu
We investigate the potential to probe new neutrino physics with future experiments measuring coherent neutrino-nucleus scattering. Experiments with high statistics should become fe…
First-order strong-field QED processes in a tightly focused laser beam
A. Di Piazza
In [Phys. Rev. Lett. \textbf{117}, 213201 (2016)] we have determined the angular resolved and the total energy spectrum of a positron produced via nonlinear Breit-Wheeler pair prod…
Package-X 2.0: A Mathematica package for the analytic calculation of one-loop integrals
Hiren H. Patel
This article summarizes new features and enhancements of the first major update of Package-X. Package-X 2.0 can now generate analytic expressions for arbitrarily high rank dimensio…
Evading Direct Dark Matter Detection in Higgs Portal Models
Giorgio Arcadi, Christian Gross, Oleg Lebedev +2
Many models of Higgs portal Dark Matter (DM) find themselves under pressure from increasingly tight direct detection constraints. In the framework of gauge field DM, we study how s…
Dark Matter Phenomenology of SM and Enlarged Higgs Sectors Extended with Vector Like Leptons
Andrei Angelescu, Giorgio Arcadi
We will investigate the scenario in which the Standard Model (SM) Higgs sector and its 2-doublet extension (called the Two Higgs Doublet Model or 2HDM) are the "portal" for the int…
Multicomponent Dark Matter from Gauge Symmetry
Giorgio Arcadi, Christian Gross, Oleg Lebedev +3
The composition of Dark Matter (DM) remains an important open question. The current data do not distinguish between single- and multi-component DM, while in theory constructions it…
Probing the scotogenic FIMP at the LHC
Andre Hessler, Alejandro Ibarra, Emiliano Molinaro +1
We analyse the signatures at the Large Hadron Collider (LHC) of the scotogenic model, when the lightest Z2-odd particle is a singlet fermion and a feebly interacting massive partic…
Perturbed Yukawa Textures in the Minimal Seesaw Model
Thomas Rink, Kai Schmitz
\noindent We revisit the \textit{minimal seesaw model}, i.e., the type-I seesaw mechanism involving only two right-handed neutrinos. % This model represents an important minimal be…
Naturalness, Vacuum Stability and Leptogenesis in the Minimal Seesaw Model
Gulab Bambhaniya, P. S. Bhupal Dev, Srubabati Goswami +2
The right-handed neutrinos within the type-I seesaw mechanism can induce large radiative corrections to the Higgs mass, and naturalness arguments can then be used to set limits on…
Isospin-violating dark matter in the light of recent data
Carlos E. Yaguna
In scenarios where the dark matter interacts differently with protons and neutrons (isospin-violating dark matter), the interpretation of the experimental limits on the dark matter…
Is the dark matter particle its own antiparticle?
Farinaldo S. Queiroz, Werner Rodejohann, Carlos E. Yaguna
We propose a test based on direct detection data that allows to determine if the dark matter particle is different from its antiparticle. The test requires the precise measurement…
Heavy right-handed neutrino dark matter in left-right models
P. S. Bhupal Dev, Rabindra N. Mohapatra, Yongchao Zhang
We show that in a class of non-supersymmetric left-right extensions of the Standard Model (SM), the lightest right-handed neutrino (RHN) can play the role of thermal Dark Matter (D…
The Liouville equation for flavour evolution of neutrinos and neutrino wave packets
Rasmus Sloth Lundkvist Hansen, Alexei Yu. Smirnov
We consider several aspects related to the form, derivation and applications of the Liouville equation (LE) for flavour evolution of neutrinos. To take into account the quantum nat…
A Call for New Physics : The Muon Anomalous Magnetic Moment and Lepton Flavor Violation
Manfred Lindner, Moritz Platscher, Farinaldo S. Queiroz
We review how the muon anomalous magnetic moment () and the quest for lepton flavor violation are intimately correlated. Indeed the decay is induced by the same amp…
Prospects for three-body Higgs boson decays into extra light scalars
Alexander J. Helmboldt, Manfred Lindner
Within models containing a very light scalar particle coupled to the 125 GeV Higgs boson, we present the first detailed study of Higgs decays into three of these light scalars. We…
Explaining Dark Matter and Decay Anomalies with an Model
Wolfgang Altmannshofer, Stefania Gori, Stefano Profumo +1
We present a dark sector model based on gauging the symmetry that addresses anomalies in decays and that features a particle dark matter candid…
Gravitational Waves as a New Probe of Bose-Einstein Condensate Dark Matter
P. S. Bhupal Dev, Manfred Lindner, Sebastian Ohmer
There exists a class of ultralight Dark Matter (DM) models which could form a Bose-Einstein condensate (BEC) in the early universe and behave as a single coherent wave instead of i…
Extracting Majorana Properties in the Throat of Neutrinoless Double Beta Decay
Shao-Feng Ge, Manfred Lindner
Assuming that neutrinos are Majorana particles, we explore what information can be inferred from future strong limits (i.e. non-observation) for neutrinoless double beta decay. Spe…
