Evidence of ghost suppression in gluon mass dynamics

A. C. Aguilar, D. Binosi, C. T. Figueiredo +1

In this work we study the impact that the ghost sector of pure Yang-Mills theories may have on the generation of a dynamical gauge boson mass, which hinges on the appearance of mas…

Direct CP violation in $K^{0} \to π π$ : Standard Model Status

Hector Gisbert, Antonio Pich

In 1988 the NA31 experiment presented the first evidence of direct CP violation in the $K^{0} \to π π$ decay amplitudes. A clear signal with a $7.2 σ$ statistical significance was late…

Singular lensing from the scattering on special space-time defects

Nick E. Mavromatos, Joannis Papavassiliou

It is well known that certain special classes of self-gravitating point-like defects, such as global (non gauged) monopoles, give rise to non-asymptotically flat space-times charac…

Leptogenesis from Heavy Right-Handed Neutrinos in CPT Violating Backgrounds

Thomas Bossingham, Nick E. Mavromatos, Sarben Sarkar

We discuss leptogenesis in a model with heavy right-handed Majorana neutrinos propagating in a constant but otherwise generic CPT-violating axial time-like background (which could…

Towards a new paradigm for heavy-light meson spectroscopy

Meng-Lin Du, Miguel Albaladejo, Pedro Fernandez-Soler +5

Since 2003 many new hadrons, including the lowest-lying positive-parity charm-strange mesons $D_{s 0}^{*} (2317)$ and $D_{s 1} (2460)$ , were observed that do not conform with quark m…

WCxf: an exchange format for Wilson coefficients beyond the Standard Model

Jason Aebischer, Ilaria Brivio, Alejandro Celis +11

We define a data exchange format for numerical values of Wilson coefficients of local operators parameterising low-energy effects of physics beyond the Standard Model. The format f…

Effective Majorana mass matrix from tau and pseudoscalar meson lepton number violating decays

Asmaa Abada, Valentina De Romeri, Michele Lucente +2

An observation of any lepton number violating process will undoubtedly point towards the existence of new physics and indirectly to the clear Majorana nature of the exchanged fermi…

Neutrinos, DUNE and the world best bound on CPT invariance

Gabriela Barenboim, Christoph Andreas Ternes, Mariam Tórtola

CPT symmetry, the combination of Charge Conjugation, Parity and Time reversal, is a cornerstone of our model building strategy and therefore the repercussions of its potential viol…

Can measurements of 2HDM parameters provide hints for high scale supersymmetry?

Gautam Bhattacharyya, Dipankar Das, M. Jay Pérez +3

Two-Higgs-doublet models (2HDMs) are minimal extensions of the Standard Model (SM) that may still be discovered at the LHC. The quartic couplings of their potentials can be determi…

Spectroscopy of the All-Charm Tetraquark

V. R. Debastiani, F. S. Navarra

We use a non-relativistic model to study the mass spectroscopy of a tetraquark composed by $c c ˉ c c ˉ$ quarks in the diquark-antidiquark picture. By numerically…

The radiative decay $D^{0} \to K ˉ^{* 0} γ$ with vector meson dominance

J. M. Dias, V. R. Debastiani, Ju-Jun Xie +1

Motivated by the experimental measurements of $D^{0}$ radiative decay modes we have proposed a model to study the $D^{0} \to K ˉ^{* 0} γ$ decay, by establishing a link with $D^0\to \b…

Can one ever prove that neutrinos are Dirac particles?

Martin Hirsch, Rahul Srivastava, José W. F. Valle

According to the "Black Box" theorem the experimental confirmation of neutrinoless double beta decay ( $0 ν 2 β$ ) would imply that at least one of the neutrinos is a Majorana particl…

Dark matter-neutrino interactions through the lens of their cosmological implications

Andres Olivares-Del Campo, Celine Boehm, Sergio Palomares-Ruiz +1

Dark matter and neutrinos provide the two most compelling pieces of evidence for new physics beyond the Standard Model of Particle Physics but they are often treated as two differe…

Probing Leptogenesis

E. J. Chun, G. Cvetič, P. S. B. Dev +12

The focus of this chapter lies on the possible experimental tests of leptogenesis scenarios. We consider both leptogenesis generated from oscillations, as well as leptogenesis from…

ARS Leptogenesis

M. Drewes, B. Garbrecht, P. Hernandez +6

We review the current status of the leptogenesis scenario originally proposed by Akhmedov, Rubakov and Smirnov (ARS). It takes place in the parametric regime where the right-handed…

Molecular $Ω_{b}$ states

Motivated by the recent finding of five $Ω_{c}$ states by the LHCb collaboration, and the successful reproduction of three of them in a recent approach searching for molecular states…

Neutrinoless double beta decay and QCD running at low energy scales

Marcela González, Martin Hirsch, Sergey Kovalenko

There is a common belief that the main uncertainties in the theoretical analysis of neutrinoless double beta ( $0 ν β β$ ) decay originate from the nuclear matrix elements. Here, we unc…

Effective alignments as building blocks of flavour models

Ivo de Medeiros Varzielas, Thomas Neder, Ye-Ling Zhou

Flavour models typically rely on flavons - scalars that break the family symmetry by acquiring vacuum expectation values in specific directions. We develop the idea of effective al…

Triangle singularity enhancing isospin violation in $B ˉ_{s}^{0} \to J / ψ π^{0} f_{0} (980)$

Wei-Hong Liang, S. Sakai, Ju-Jun Xie +1

We perform calculations for the $B ˉ_{s}^{0} \to J / ψ π^{0} f_{0} (980)$ and $B ˉ_{s}^{0} \to J / ψ π^{0} a_{0} (980)$ reactions, showing that the first one is isospin-suppressed while the second o…

Hidden charm pentaquark and $Λ (1405)$ in the $Λ_{b}^{0} \to η_{c} K^{-} p (π Σ)$ reaction

Ju-Jun Xie, Wei-Hong Liang, Eulogio Oset

We have performed a study of the $Λ_{b}^{0} \to η_{c} K^{-} p$ and $Λ_{b}^{0} \to η_{c} π Σ$ reactions based on the dominant Cabibbo favored weak decay mechanism. We show that the $K^{-} p$ produce…

Stable heavy pentaquarks in constituent models

J. -M. Richard, A. Valcarce, J. Vijande

It is shown that standard constituent quark models produce $(c ˉ c q q q)$ hidden-charm pentaquarks, where $c$ denotes the charmed quark and $q$ a light quark, which lie below the…

The Dark Side of Flipped Trinification

P. V. Dong, D. T. Huong, Farinaldo S. Queiroz +2

We propose a model which unifies the Left-Right symmetry with the $S U (3)_{L}$ gauge group, called flipped trinification, and based on the $SU(3)_C\otimes SU(3)_L\otimes SU(3)_R\otime…

Flavour-symmetric type-II Dirac neutrino seesaw mechanism

Cesar Bonilla, J. M. Lamprea, Eduardo Peinado +1

We propose a Standard Model extension with underlying A4 flavour symmetry where small Dirac neutrino masses arise from a Type-II seesaw mechanism. The model predicts the "golden" f…
