A Consistent Path Integral Approach to Higher Derivative Oscillators
Jose A. R. Cembranos, Eric G. Hemon, Juan J. Sanz-Cillero
In this work, we study the Quantum Field Theory version of the higher derivative Pais-Uhlenbeck oscillator. We quantize canonically this system and construct its Fock space, as wel…
Sensitivity forecasts for gravitational-wave detectors to dark matter decaying into gravitons
Jose A. R. Cembranos, Álvaro Cendal
Dark matter may not be perfectly stable, and its decay could generate distinctive gravitational-wave signatures. In this work, we present model-independent predictions for the stoc…
Scalar Dark Matter Production through the Bubble Expansion Mechanism:The Role of the Lorentz factor and Non-Renormalizable Interactions
Jose A. R. Cembranos, Jesús Luque, Javier Rubio
We consider a Bubble Expansion mechanism for the production of scalar dark matter during a first-order phase transition in the very early Universe. Seeking for a dark matter energy…
Constraining the General Oscillatory Inflaton Potential with Freeze-in Dark Matter and Gravitational Waves
Jose A. R. Cembranos, Mindaugas Karčiauskas
The reheating phase after inflation is one of the least observationally constrained epochs in the evolution of the Universe. The forthcoming gravitational wave observatories will e…
The Invisible Dilaton
Philippe Brax, Clare Burrage, Jose A. R. Cembranos +1
We analyse the dynamics of a light scalar field responsible for the term of the Higgs potential and coupled to matter via the Higgs-portal mechanism. We find that this dilaton…
Gravitational Coleman-Weinberg Mechanism
Clara Álvarez-Luna, Sergio de la Calle-Leal, José A. R. Cembranos +1
The Coleman-Weinberg mechanism provides a procedure by which a scalar field, which initially has no mass parameters, acquires a mass due to the anomalous nature of scale symmetry.…
SKA-Phase 1 sensitivity for synchrotron radio emission from multi-TeV Dark Matter candidates
J. A. R. Cembranos, A. de la Cruz-Dombriz, V. Gammaldi +1
In the era of radio astronomy, the high sensitivity of the Square Kilometre Array (SKA) could play a decisive role in the detection of new radio sources. In this work, we study the…
Constraints on hidden gravitons from fifth-force experiments and stellar energy loss
J. A. R. Cembranos, A. L. Maroto, H. Villarrubia-Rojo
We study different phenomenological signatures associated with new spin-2 particles. These new degrees of freedom, that we call hidden gravitons, arise in different high-energy the…
Reliability of Monte Carlo event generators for gamma ray dark matter searches
J. A. R. Cembranos, A. de la Cruz-Dombriz, V. Gammaldi +2
We study the differences in the gamma ray spectra simulated by four Monte Carlo event generator packages developed in particle physics. Two different versions of PYTHIA and two of…
Minimal Universal Extra Dimensions
Jose A. R. Cembranos, Jonathan L. Feng, Louis E. Strigari
Highly degenerate spectra associated with universal extra dimensions (UED) provide an interesting phenomenology not only from the point of view of cosmology and astrophysics, but a…
Exotic Collider Signals from the Complete Phase Diagram of Minimal Universal Extra Dimensions
Jose A. R. Cembranos, Jonathan L. Feng, Louis E. Strigari
Minimal universal extra dimensions (mUED) is often thought to predict that the lightest Kaluza-Klein particle (LKP) is the Kaluza-Klein gauge boson B^1, leading to conventional mis…
Some model-independent phenomenological consequences of flexible brane worlds
J. A. R. Cembranos, A. Dobado, A. L. Maroto
In this work we will review the main properties of brane-world models with low tension. Starting from very general principles, it is possible to obtain an effective action for the…
Searching for CPT violation in top anti-top production
J. A. R. Cembranos, A. Rajaraman, F. Takayama
We analyze the possibility of observing CPT violation in the top sector. We present current bounds on CPT violation in this sector, and analyze the prospects of improving these bou…
Toward High Precision Higgs-Boson Measurements at the International Linear e+e- Collider
S. Heinemeyer, S. Kanemura, H. Logan +31
This report reviews the properties of Higgs bosons in the Standard Model (SM) and its various extensions. We give an extensive overview about the potential of the ILC operated at c…
Branon search in hadronic colliders
J. A. R. Cembranos, A. Dobado, A. L. Maroto
In the context of the brane-world scenarios with compactified extra dimensions, we study the production of brane fluctuations (branons) in hadron colliders (, and $e…
Brane-world dark matter
J. A. R. Cembranos, A. Dobado, A. L. Maroto
We show that, in the context of brane-world scenarios with low tension , massive brane fluctuations are natural dark matter candidates. We calculate the present abundances f…
