Do neutrino oscillations allow an extra phenomenological parameter? [PDF]
JETP Lett. 73 (2001) 380; Pisma Zh.Eksp.Teor.Fiz. 73 (2001) 424, 2001 The quantity $\xi$ introduced recently in the phenomenological description of neutrino oscillations is in fact not a free parameter, but a fixed number.

The Chiral Induced Spin Selectivity Effect What It Is, What It Is Not, And Why It Matters
Israel Journal of Chemistry, Volume 62, Issue 11-12, December 2022., 2022 Abstract The chiral induced spin selectivity effect is an excited states phenomenon, which can be probed using photo‐spectroscopy as well as transport measurements. On the one hand such measurements represent averaged quantities, on the other hand nearly all theoretical descriptions, with only a few exceptions, have been concerned with energy dependent

Reconstruction of top-quark mass effects in Higgs pair production and other gluon-fusion processes
Journal of High Energy Physics, 2018 We propose a novel method for the treatment of top-quark mass effects in the production of H (∗), HH, HZ and ZZ final states in gluon fusion. We show that it is possible to reconstruct the full top-quark mass dependence of the virtual amplitudes from the

Phenomenology of the little flavon model [PDF]
Phys.Rev. D70 (2004) 013002, 2004 The phenomenology of the little-flavon model is discussed. Flavor changing neutral current and lepto-quark compositeness set the most stringent bounds to the lowest possible value for the scale at which the flavons arise as pseudo-Goldstone bosons.

Journal of High Energy Physics, 2021 We present a framework for the construction of portal effective theory (PETs) that couple effective field theories of the Standard Model (SM) to light hidden messenger fields.

Statistical hadronisation phenomenology [PDF]
, 2002 The analyses of hadron production in the framework of the statistical hadronisation model are reviewed. The analysis of average multiplicities in collisions at relatively low centre-of-mass energy confirms previous findings, namely the universality of ...

Quarkonium photoproduction in pp and AA collisions at the LHC
EPJ Web of Conferences, 2016 In this contribution we report on the investigations of the exclusive production of quarkonium states in proton-proton and nucleus-nucleus reactions at the LHC using the theoretical framework of the light-cone dipole formalism.

Potential and limitations of machine-learning approaches to inclusive |V ub | determinations
Journal of High Energy Physics, 2022 The determination of |V ub | in inclusive semileptonic B → X u ℓν decays will be among the pivotal tasks of Belle II. In this paper we study the potential and limitations of machine-learning approaches that attempt to reduce theory uncertainties by ...

Sensemaking reconsidered : towards a broader understanding through phenomenology [PDF]
, 2020 We develop a typology of sensemaking in organizations that reconsiders existing sensemaking research by providing a more coherent and integrative conceptualization of what defines sensemaking and how it is connected with organizing.

MeV-scale sterile neutrino decays at the Fermilab Short-Baseline Neutrino program
Journal of High Energy Physics, 2017 Nearly-sterile neutrinos with masses in the MeV range and below would be produced in the beam of the Short-Baseline Neutrino (SBN) program at Fermilab. In this article, we study the potential for SBN to discover these particles through their subsequent ...
