Six top messages of new physics at the LHC
Journal of High Energy Physics, 2019 Six top signatures provide a novel probe of new physics. We discuss production of six top quarks as the decay products of a pair of top partners in the setting of a composite Higgs model, and argue that the six top signal may generically provide one of ...

Decaying Dark Atom Constituents and Cosmic Positron Excess
Advances in High Energy Physics, Volume 2014, Issue 1, 2014., 2014 We present a scenario where dark matter is in the form of dark atoms that can accommodate the experimentally observed excess of positrons in PAMELA and AMS‐02 while being compatible with the constraints imposed on the gamma‐ray ux from Fermi/LAT. This scenario assumes that the dominant component of dark matter is in the form of a bound state between a ...

Journal of High Energy Physics, 2017 We show a symmetry that, in the context of a composite Higgs with anarchic flavor, can suppress the dominant CP violating contributions to K − K ¯ $$ K-\overline{K} $$ mixing.

When should firms watch for cross‐industry competition? A demand‐side perspective
Strategic Management Journal, Volume 47, Issue 3, Page 893-941, March 2026.Abstract Research Summary Research on competitor identification has primarily focused on intra‐industry competition. However, cross‐industry competitive threats are prevalent and consequential. We adopt a consumer‐oriented perspective to examine how consumer perceptions shape de facto competition across industry boundaries.

Probes for 4th Generation Constituents of Dark Atoms in Higgs Boson Studies at the LHC
Advances in High Energy Physics, Volume 2014, Issue 1, 2014., 2014 The nonbaryonic dark matter of the Universe can consist of new stable charged species, bound in heavy neutral “atoms” by ordinary Coulomb interaction. Stable U- (anti‐U)quarks of 4th generation, bound in stable colorless (U- U- U-) clusters, are captured by the primordial helium, produced in Big Bang Nucleosynthesis, thus forming neutral “atoms” of O ...

Composite 2HDM with singlets: a viable dark matter scenario
Journal of High Energy Physics, 2019 We study the non-minimal composite Higgs model with global symmetry SO(7) broken to SO(5) × SO(2). The model results in a composite Two-Higgs doublet model (2HDM) equipped with two extra singlets, the lightest of which can be a viable dark matter ...

Emerging jets displaced into the future
Journal of High Energy Physics, 2022 We examine the potential of future long-lived particle experiments to probe dark QCD models that feature Emerging Jets. The core of this analysis focuses on the transverse detectors AL3X, ANUBIS, CODEX-b, and MATHUSLA as they cover the most relevant ...

Neutrino Magnetic Moment in the Doublet‐Singlet Leptoquark Model
Advances in High Energy Physics, Volume 2026, Issue 1, 2026.The transition magnetic moment for Majorana neutrinos is studied in a simple extension of the Standard Model. This extension incorporates two scalar Leptoquarks S1 and R~2 with quantum numbers 3¯,113,/ and (3, 2, 1/6), respectively. It is found that these Leptoquarks generate a sizable transition magnetic moment, particularly when the quark bottom is ...

Probing the Top Quark Flavour‐Changing Neutral Current at a Future Electron‐Positron Collider
Advances in High Energy Physics, Volume 2014, Issue 1, 2014., 2014 We present a study to examine the sensitivity of a future e−e+ collider to the anomalous top flavour‐changing neutral current (FCNC) to the gluon. To separate signal from background a multivariate analysis is performed on top quark pair and background events, where one top quark is considered to follow the dominant standard model (SM) decay, t → Wb ...

Anarchy with linear and bilinear interactions
Journal of High Energy Physics, 2017 Composite Higgs models with anarchic partial compositeness require a scale of new physics O 10 − 100 $$ \mathcal{O}\left(10-100\right) $$ TeV, with the bounds being dominated by the dipole moments and ϵ K .
