An EFT study of the process at the FCC-
Shankha Banerjee, Rick S. Gupta, Shilpi Jain +2
We carry out an Effective Field Theory (EFT) study of the process in the $4b + 3 \ell + \ge 2j + \slashed{E}_T$ final state. This process can uniquely probe t…
On the Dynamical Origin of the Potential and the Axion Mass
Csaba Csáki, Raffaele Tito D'Agnolo, Rick S. Gupta +3
We investigate the dynamics responsible for generating the potential of the , the (would-be) Goldstone boson associated with the anomalous axial symmetry of QCD. The sta…
Probing Poincaré Violation
Rick S. Gupta, Joerg Jaeckel, Michael Spannowsky
Time and space translation invariance, giving rise to energy and momentum conservation, are not only amongst the most fundamental but also the most generally accepted symmetry assu…
Running away from the T-parameter solution to the W mass anomaly
Rick S. Gupta
We show that it is essential to include renormalisation group (RG) effects for determining the SMEFT parameter space consistent with the CDF W-mass anomaly at the matching scale. T…
High energy lepton colliders as the ultimate Higgs microscopes
Shankha Banerjee, Rick S. Gupta, Oscar Ochoa-Valeriano +1
We study standard electroweak/Higgs processes at the high-energy lepton colliders ILC and CLIC. We identify a subset of three operators in the SMEFT that give leading contributions…
A fully differential SMEFT analysis of the golden channel using the method of moments
Shankha Banerjee, Rick S. Gupta, Oscar Ochoa-Valeriano +2
The Method of Moments is a powerful framework to disentangle the relative contributions of amplitudes of a specific process to its various phase space regions. We apply this method…
Precision SMEFT bounds from the VBF Higgs at high transverse momentum
Jack Y. Araz, Shankha Banerjee, Rick S. Gupta +1
We study the production of Higgs bosons at high transverse momenta via vector-boson fusion (VBF) in the Standard Model Effective Field Theory (SMEFT). We find that contributions fr…
Towards the ultimate differential SMEFT analysis
Shankha Banerjee, Rick S. Gupta, Joey Y. Reiness +2
We obtain SMEFT bounds using an approach that utilises the complete multi-dimensional differential information of a process. This approach is based on the fact that at a given EFT…
On the Wondrous Stability of ALP Dark Matter
Gonzalo Alonso-Álvarez, Rick S. Gupta, Joerg Jaeckel +1
The very low mass and small coupling of axion-like particles (ALPs) is usually taken as a guarantor of their cosmological longevity, making them excellent dark matter candidates. T…
Resolving the tensor structure of the Higgs coupling to -bosons via Higgs-strahlung
Shankha Banerjee, Rick S. Gupta, Joey Y. Reiness +1
We propose differential observables for that can be used to completely determine the tensor structure of the couplings releva…
Out-of-the-box Baryogenesis During Relaxation
S. A. Abel, R. S. Gupta, J. Scholtz
We show that spontaneous baryogenesis occurs automatically in relaxion models if the reheating temperature is larger than the weak scale, provided the Standard Model fields are cha…
Probing Electroweak Precision Physics via boosted Higgs-strahlung at the LHC
Shankha Banerjee, Christoph Englert, Rick S. Gupta +1
We study the process in the Standard Model Effective Field Theory (SMEFT) at high energies using subjet techniques to reconstruct the Higgs boso…
The Hierarchion, a Relaxion Addressing the Standard Model's Hierarchies
Oz Davidi, Rick S. Gupta, Gilad Perez +2
We present a mechanism that addresses the electroweak, the strong CP, and the flavor hierarchies of the Standard Model (including neutrino masses) in a unified way. The naturalness…
The Relaxion Measure Problem
Rick S. Gupta
We examine the necessity of requiring that relaxion dynamics is dominated by classical slow roll and not quantum fluctuations. It has been recently proposed by Nelson and Prescod-W…
The Nelson-Barr Relaxion
Oz Davidi, Rick S. Gupta, Gilad Perez +2
Cosmological relaxation models in which the relaxion is identified with the QCD axion, generically fail to account for the smallness of the strong CP phase. We present a simple alt…
Phenomenology of relaxion-Higgs mixing
Thomas Flacke, Claudia Frugiuele, Elina Fuchs +2
We show that the relaxion generically stops its rolling at a point that breaks CP leading to relaxion-Higgs mixing. This opens the door to a variety of observational probes since t…
Interpreting a 750 GeV Diphoton Resonance
Rick S. Gupta, Sebastian Jäger, Yevgeny Kats +2
We discuss the implications of the significant excesses in the diphoton final state observed by the LHC experiments ATLAS and CMS around a diphoton invariant mass of 750 GeV. The i…
Is the Relaxion an Axion?
Rick S. Gupta, Zohar Komargodski, Gilad Perez +1
We consider the recently proposed cosmological relaxation mechanism where the hierarchy problem is ameliorated, and the electroweak scale is dynamically selected by a slowly rollin…
Is the Higgs Mechanism of Fermion Mass Generation a Fact? A Yukawa-less First-Two-Generation Model
Diptimoy Ghosh, Rick Sandeepan Gupta, Gilad Perez
It is now established that the major source of electroweak symmetry breaking (EWSB) is due to the observed Higgs particle. However, whether the Higgs mechanism is responsible for t…
BSM Primary Effects: The complete set of predictions from the dimension-6 BSM Lagrangian
Rick S. Gupta
We present a physical parameterization of the leading effects beyond the SM (BSM), that give us, at present, the best way to constrain heavy new-physics at low-energies. We call th…
BSM Primary Effects
Rick S. Gupta, Alex Pomarol, Francesco Riva
Using the predictive power of the effective field theory approach, we present a physical parametrization of the leading effects beyond the SM (BSM), that give us at present the bes…
Scaling and tuning of EW and Higgs observables
Joan Elias-Miro, Christophe Grojean, Rick S. Gupta +1
We study deformations of the SM via higher dimensional operators. In particular, we explicitly calculate the one-loop anomalous dimension matrix for 13 bosonic dimension-6 operator…
BSM Theories Face Higgs Coupling data
Rick S. Gupta
We discuss how much Higgs couplings (including the Higgs self coupling) can deviate from their Standard Model values, in different Beyond Standard Model (BSM) theories, if no other…
How well do we need to measure the Higgs boson mass and self-coupling?
Rick S. Gupta, Heidi Rzehak, James D. Wells
Much of the discussion regarding future measurements of the Higgs boson mass and self-coupling is focussed on how well various collider options can do. In this article we ask a phy…
