Probing Poincaré violation (2023)
Journal Article
Gupta, R., Jaeckel, J., & Spannowsky, M. (2023). Probing Poincaré violation. Journal of High Energy Physics, 2023(11), 26. https://doi.org/10.1007/jhep11%282023%29026

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 assumptions in physics. It is nevertheless prudent to put such assumptions... Read More about Probing Poincaré violation.

Precision SMEFT bounds from the VBF Higgs at high transverse momentum (2021)
Journal Article
Araz, J. Y., Banerjee, S., Gupta, R. S., & Spannowsky, M. (2021). Precision SMEFT bounds from the VBF Higgs at high transverse momentum. Journal of High Energy Physics, 2021(4), Article 125. https://doi.org/10.1007/jhep04%282021%29125

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 from four independent operator combinations dominate in this limit. Thes... Read More about Precision SMEFT bounds from the VBF Higgs at high transverse momentum.

Towards the ultimate differential SMEFT analysis (2020)
Journal Article
Banerjee, S., Gupta, R. S., Reiness, J. Y., Seth, S., & Spannowsky, M. (2020). Towards the ultimate differential SMEFT analysis. Journal of High Energy Physics, 2020(9), https://doi.org/10.1007/jhep09%282020%29170

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 order, the full angular distribution in the most important electroweak... Read More about Towards the ultimate differential SMEFT analysis.

Nelson-Barr relaxion (2019)
Journal Article
Davidi, O., Gupta, R. S., Perez, G., Redigolo, D., & Shalit, A. (2019). Nelson-Barr relaxion. Physical Review D, 99(3), Article 035014. https://doi.org/10.1103/physrevd.99.035014

Cosmological relaxation models in which the relaxion is identified with the QCD axion, generically fail to account for the smallness of the strong C P phase. We present a simple alternative solution to this “relaxion C P problem” based on the Nelson-... Read More about Nelson-Barr relaxion.

Probing electroweak precision physics via boosted Higgs-strahlung at the LHC (2018)
Journal Article
Banerjee, S., Englert, C., Gupta, R. S., & Spannowsky, M. (2018). Probing electroweak precision physics via boosted Higgs-strahlung at the LHC. Physical Review D, 98(9), Article 095012. https://doi.org/10.1103/physrevd.98.095012

We study the process pp → Zðlþl−Þhðbb¯Þ in the standard model effective field theory (SMEFT) at high energies using subjet techniques to reconstruct the Higgs boson. We show that at high energies this process probes four directions in the dimension-6... Read More about Probing electroweak precision physics via boosted Higgs-strahlung at the LHC.

Relaxion measure problem (2018)
Journal Article
Gupta, R. S. (2018). Relaxion measure problem. Physical Review D, 98(5), Article 055023. https://doi.org/10.1103/physrevd.98.055023

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-Weinstein [Phys. Rev. D 96, 113007 (2017)] that abandoning this require... Read More about Relaxion measure problem.

The hierarchion, a relaxion addressing the Standard Model’s hierarchies (2018)
Journal Article
Davidi, O., Gupta, R. S., Perez, G., Redigolo, D., & Shalit, A. (2018). The hierarchion, a relaxion addressing the Standard Model’s hierarchies. Journal of High Energy Physics, 2018(8), Article 153. https://doi.org/10.1007/jhep08%282018%29153

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 of the electroweak scale is solved together with the strong CP proble... Read More about The hierarchion, a relaxion addressing the Standard Model’s hierarchies.
