Proceedings to the 28th Workshop What Comes Beyond the Standard Models
Norma Susana Mankoč Borštnik, Holger Bech Nielsen, Maxim Yu. Khlopov +1
This year was 28th time that our series of workshops entitled "What Comes Beyond the Standard Models?" took place. The series started in 1998 with the idea of organising a workshop…
Chemical evolution of antimatter domains in early Universe
A. I. Dembitskaia, Stephane Weiss, M. Yu. Khlopov +1
According to modern physics, our Universe is baryon-asymmetric. That phenomenon can not be described in the frameworks of the Standard Model of particle physics. Globally, the Univ…
Probing Lorentz Invariance Violation at High-Energy Colliders via Intermediate Massive Boson Mass Measurements: Z Boson Example
Z. Kepuladze, J. Jejelava
Lorentz invariance (LI) is a foundational principle of modern physics, yet its possible violation (LIV) remains an intriguing window to physics beyond the Standard Model. While str…
How to present and interpret the Feynman diagrams in this theory describing fermion and boson fields in a unique way, in comparison with the Feynman diagrams so far presented and interpreted?
N. S. Mankoč Borštnik, H. B. Nielsen
Although the internal spaces describing spins and charges of fermions' and bosons' second-quantised fields have such different properties, yet we can all describe them equivalently…
Spontaneous baryosynthesis with large initial phase
Maxim Krasnov, Maxim Khlopov, Ufuk Aydemir
We numerically investigate particle production by a pseudo-Nambu-Goldstone boson (pNGB) in spontaneous baryogenesis, focusing on large initial misalignment angles. Our analysis con…
Unified Pati-Salam from Noncommutative Geometry: Overview and Phenomenological Remarks
Ufuk Aydemir
The lack of clear new-physics signals at the LHC searches motivates models that can guide current and future collider searches. The spectral action principle within the noncommutat…
Spontaneous baryogenesis with large misalignment
Maxim Krasnov, Ufuk Aydemir, Maxim Khlopov
We investigate particle production by a pseudo-Nambu-Goldstone boson (pNGB) in the spontaneous baryogenesis scenario for large misalignment angles. Since the fermionic backreaction…
Diffeomorphism Invariance Breaking in Gravity and Cosmological Evolution
Ufuk Aydemir, Mahmut Elbistan
Diffeomorphism invariance breaking has been investigated in the literature in several contexts, including emergent General Relativity (GR). If GR emerges from an underlying theory…
Axion dark matter with not quite black hole domination
Ufuk Aydemir
We investigate the effects of an early cosmological period dominated by primordial 2-2-holes on axion dark matter. The 2-2-holes emerge as a new family of horizonless classical sol…
An economical model for -flavour and anomalies from SO(10) grand unification
Ufuk Aydemir, Tanumoy Mandal, Subhadip Mitra +1
We investigate an grand unification scenario where the complex 10-dimensional scalar multiplet, containing the Standard Model (SM) Higgs boson, resides at the TeV…
On thermodynamics of compact objects
Ufuk Aydemir, Jing Ren
With the recent progress in observations of astrophysical black holes, it has become more important to understand in detail the physics of strongly gravitating horizonless objects.…
Dark sector production and baryogenesis from not quite black holes
Ufuk Aydemir, Jing Ren
Primordial black holes have been considered as an attractive dark matter candidate, whereas some of the predictions heavily rely on the near-horizon physics that remains to be test…
Primordial Black-Hole Mimicker in Quadratic Gravity as Dark Matter
Ufuk Aydemir
We discuss the astrophysical and cosmological implications of having primordial thermal 2-2-hole remnants as dark matter. Thermal 2-2-holes emanate in quadratic gravity as horizonl…
Not quite black holes as dark matter
Ufuk Aydemir, Bob Holdom, Jing Ren
Primordial black holes that survive until the present have been considered as a dark matter candidate. In this paper we argue that primordial 2-2-hole remnants provide a more promi…
Addressing the anomalies with an leptoquark from grand unification
Ufuk Aydemir, Tanumoy Mandal, Subhadip Mitra
Motivated by the anomalies, we investigate an grand unification scenario where a charge scalar leptoquark () remains as the only new phy…
Clifford-based spectral action and renormalization group analysis of the gauge couplings
Ufuk Aydemir
The Spectral Action Principle in noncommutative geometry derives the actions of the Standard Model and General Relativity (along with several other gravitational terms) by reconcil…
-decay anomalies and scalar leptoquarks in unified Pati-Salam models from noncommutative geometry
Ufuk Aydemir, Djordje Minic, Chen Sun +1
Motivated by possible scalar-leptoquark explanations of the recently reported -decay anomalies, we investigate whether the required leptoquarks can be accommodated within models…
A scale at 10 MeV, gravitational topological vacuum, and large extra dimensions
Ufuk Aydemir
We discuss a possible scale of gravitational origin at around MeV, or cm, which arises in the MacDowell-Mansouri formalism of gravity due to the topological Gauss-B…
The 750 GeV diphoton excess in unified models from noncommutative geometry
Ufuk Aydemir, Djordje Minic, Chen Sun +1
We discuss a possible interpretation of the GeV diphoton resonance, recently reported at the LHC, within a class of models with gauge coup…
LHC probes of TeV-scale scalars in grand unification
Ufuk Aydemir, Tanumoy Mandal
We investigate the possibility of TeV-scale scalars as low energy remnants arising in the non-supersymmetric grand unification framework where the field content i…
SO(10) grand unification in light of recent LHC searches and colored scalars at the TeV-scale
Ufuk Aydemir
We analyze the compatibility of the recent LHC signals and the TeV-scale left-right model(s) in the minimal nonsupersymmetric framework. We show that the models in which t…
Pati-Salam Unification from Non-commutative Geometry and the TeV-scale boson
Ufuk Aydemir, Djordje Minic, Chen Sun +1
We analyze the compatibility of the unified left-right symmetric Pati-Salam models motivated by non-commutative geometry and the TeV scale right-handed W boson suggested by recent…
The Higgs Mass, Superconnections and the TeV-scale Left-Right Symmetric Model
Ufuk Aydemir, Djordje Minic, Chen Sun +1
We discuss the physical implications of formulating the Standard Model (SM) in terms of the superconnection formalism involving the superalgebra su(2/1). In particular, we discuss…
The Higgs Mass and the Emergence of New Physics
Ufuk Aydemir, Djordje Minic, Tatsu Takeuchi
We investigate the physical implications of formulating the electroweak (EW) part of the Standard Model (SM) in terms of a superconnection involving the supergroup SU(2/1). In part…
