Physics reach of MoEDAL at LHC: magnetic monopoles, supersymmetry and beyond
Nick E. Mavromatos, Vasiliki A. Mitsou
MoEDAL is a pioneering experiment designed to search for highly ionising messengers of new physics such as magnetic monopoles or massive (pseudo-)stable charged particles, that are…
The signal of ill-defined CPT weakening entanglement in the system
Jose Bernabeu, Francisco J. Botella, Nick E. Mavromatos +1
In the presence of quantum gravity fluctuations (space-time foam), the CPT operator may be ill-defined. Its perturbative treatment leads to a modification of the Einstein-Podolsky-…
Precision physics with QCD
Antonio Pich
The four-loop determination of the strong coupling from fully inclusive observables is reviewed. Special attention is given to the low-energy measurement extracted from the hadroni…
Threshold effects in P-wave bottom-strange mesons
Pablo G. Ortega, Jorge Segovia, David R. Entem +1
Using a nonrelativistic constituent quark model in which the degrees of freedom are quark-antiquark and meson-meson components, we have recently shown that the thresh…
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…
CP-violating decays of the pseudoscalars eta and eta' and their connection to the electric dipole moment of the neutron
Thomas Gutsche, Astrid N. Hiller Blin, Sergey Kovalenko +4
Using the present upper bound on the neutron electric dipole moment, we give an estimate for the upper limit of the CP-violating couplings of the eta(eta') to the nucleon. Using th…
Lowest lying even-parity mesons: heavy quark spin-flavor symmetry, chiral dynamics, and constituent quark model bare masses
Miguel Albaladejo, Pedro Fernandez-Soler, Juan Nieves +1
The discovery of the and resonances in the charmed-strange meson spectra revealed that formerly successful constituent quark models lose predicta…
Scalar contributions to transitions
Alejandro Celis, Martin Jung, Xin-Qiang Li +1
We perform a comprehensive analysis of scalar contributions in transitions including the latest measurements of , the differential distributions in $…
Probing CP violation with non-unitary mixing in long-baseline neutrino oscillation experiments: DUNE as a case study
F. J. Escrihuela, D. V. Forero, O. G. Miranda +2
When neutrino masses arise from the exchange of neutral heavy leptons, as in most seesaw schemes, the effective lepton mixing matrix describing neutrino propagation is non-unit…
Updated Collider and Direct Detection Constraints on Dark Matter Models for the Galactic Center Gamma-Ray Excess
Miguel Escudero, Dan Hooper, Samuel J. Witte
Utilizing an exhaustive set of simplified models, we revisit dark matter scenarios potentially capable of generating the observed Galactic Center gamma-ray excess, updating constra…
Gauge vectors and double beta decay
Renato M. Fonseca, Martin Hirsch
We discuss contributions to neutrinoless double beta () decay involving vector bosons. The starting point is a list of all possible vector representations that may contribute…
Neutrino-induced one-pion production revisited: the channel
E. Hernández, J. Nieves
Understanding single pion production reactions on free nucleons is the first step towards a correct description of these processes in nuclei, which are important for signal and bac…
Integrating out resonances in strongly-coupled electroweak scenarios
Ignasi Rosell, Antonio Pich, Joaquin Santos +1
Accepting that there is a mass gap above the electroweak scale, the Electroweak Effective Theory (EWET) is an appropriate tool to describe this situation. Since the EWET couplings…
- and - transition form factors in a nonlocal NJL model
D. Gomez Dumm, S. Noguera, N. N. Scoccola
We study the and distribution amplitudes (DAs) in the context of a nonlocal SU(3)_L x SU(3)_R chiral quark model. The corresponding Lagrangian allows to reproduce the phen…
The right top coupling in the aligned two-Higgs-doublet model
Cesar Ayala, Gabriel A. González-Sprinberg, R. Martinez +1
We compute the right top quark coupling in the aligned two-Higgs-doublet model. In the Standard Model the real part of this coupling is dominated by QCD-gluon-exchange diagram, but…
Revising the resonance
V. R. Debastiani, F. Aceti, Wei-Hong Liang +1
We have studied the production and decay of the into and as a function of the mass of the resonance and find a shoulder around 1400 MeV, tied t…
Computation of NLO Processes Involving Heavy Quarks Using Loop-Tree Duality
Felix Driencourt-Mangin
We present a new method to compute higher-order corrections to physical cross-sections, at Next-to-Leading Order and beyond. This method, based on the Loop Tree Duality, leads to l…

Wei-Hong Liang, Eulogio Oset, Zhu-Sheng Xie
We evaluate the partial decay widths for the semileptonic and decays from the perspective that these two reson…

P. González
Strong decays of are analyzed from two quark model descriptions of , a conventional one in terms of the Cornell potential and an unconv…
Perspectives for Detecting Lepton Flavour Violation in Left-Right Symmetric Models
Cesar Bonilla, Manuel E. Krauss, Toby Opferkuch +1
We investigate lepton flavour violation in a class of minimal left-right symmetric models where the left-right symmetry is broken by triplet scalars. In this context we present a m…
The seesaw path to leptonic CP violation
A. Caputo, P. Hernandez, M. Kekic +2
Future experiments such as SHiP and high-intensity colliders will have a superb sensitivity to heavy Majorana neutrinos with masses below . We show that the measurem…

Mario Reig, José W. F. Valle, C. A. Vaquera-Araujo
We suggest a new left-right symmetric model implementing a low-scale seesaw mechanism in which quantum consistency requires three families of fermions. The symmetry breaking route…
