The Overlooked Threat of Global Warming on Elasmobranch Fertility

open access: yesFish and Fisheries, Volume 27, Issue 1, Page 41-55, January 2026.
ABSTRACT Climate change is increasingly recognised as a critical threat to global biodiversity, yet its impacts on reproductive processes remain poorly understood in many marine taxa. Elasmobranchs (sharks, skates and rays) represent a particularly vulnerable group due to their peculiar life histories, low fecundity, and diverse reproductive modes.

Complete two-loop Yukawa-induced running of the Higgs-gluon coupling in SMEFT

open access: yesJournal of High Energy Physics
We compute the two-loop renormalisation group equation for the effective Higgs to gluon coupling in Standard Model Effective Field Theory. Concretely, we present the contributions generated by the operators belonging to class 3 and 7 in the Warsaw basis,

Single Higgs production at LHC as a probe for an anomalous Higgs self coupling [PDF]

open access: yesProceedings of 38th International Conference on High Energy Physics — PoS(ICHEP2016), 2017
We explore the possibility of probing the trilinear Higgs self coupling indirectly, through single Higgs production and decay processes. The method relies on the effects that electroweak loops featuring an anomalous trilinear coupling would imprint on single Higgs production at the LHC.

Dynamical Dark Sector: A Joint Two‐Scalar‐Field Model for Dark Matter and Quintessence

open access: yesAdvances in Astronomy, Volume 2026, Issue 1, 2026.
The physical nature of dark matter and dark energy remains one of the most pressing questions in modern cosmology. This work presents a phenomenological model where the entire dark sector is described by two minimally coupled scalar fields within general relativity.

Neutrino Magnetic Moment in the Doublet‐Singlet Leptoquark Model

open access: yesAdvances 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 ...

Higgs and collider phenomenology of physics beyond the standard model

open access: yes, 2013
This thesis explores three classes of beyond-the-Standard Model (BSM) theories: Minimal Universal Extra Dimensions (MUED), the 4D Composite Higgs Model (4DCHM) and Technicolor.

Anomalous Higgs Couplings at Colliders

open access: yes, 1998
I summarize our results on the attainable limits on the coefficients of dimension-6 operators from the analysis of Higgs boson phenomenology using data taken at Tevatron RUNI and LEPII. Our results show that the coefficients of Higgs-vector boson couplings can be determined with unprecedented accuracy.

Sensitivity study of anomalous HZZ couplings at a future Higgs factory *

open access: yesChinese Physics C, 2019
Abstract We study the sensitivity of constraining the model independent H ZZ coupling based on the effective theory up to dimension-6 operators at a future Higgs factory. Using the current conceptual design parameters of the Circular Electron Positron Collider, we give the experimental limits for the model independent ...
