“…The production cross sections of the different sparticle species are rather different and often determine the exclusion or detection power of a particular channel. For instance, the strongest exclusion limits at the LHC across the sparticle spectrum are on first and second generation squarks and gluinos which, as can be seen in Figure 9, have the largest production cross sections [370,371].…”

GUT Physics in the Era of the LHC

Grand Unified Theories (GUTs) are one of the most interesting high-energy completions of the Standard Model, because they provide a rich, powerful and elegant group-theoretical framework able to resolve a variety of problems remaining in our current understanding of particle physics. They usually act as motivators for many low energy BSM theories, such as left-right symmetric or supersymmetric models, and they serve to fill the gap between the experimentally reachable low energies and the physics in the ultraviolet. In recent years, however, they have fallen slightly from the spotlight, in favour of "simplified" models with more specific phenomenological predictions. The aim of this review is to summarize the state of the art on GUTs and argue for their importance in modern physics. Recent advances in experiments permit to test the predictions of GUTs at different energy scales. First, as GUTs can play a role in the inflationary dynamics of the early Universe, their imprints could be found in the CMB observations by the Planck satellite. Remarkably enough, GUTs could manifest themselves also in terrestrial tests; several planned experiments aim to probe the proton stability and to establish order of magnitude higher bounds on its lifetime. Moreover, the predictions of specific GUT models could be tested even at the LHC thanks to its high energy reach, via searches for exotic states or additional contributions to flavour anomalies.

“…Indeed, nearly a dozen of experimental analyses [1][2][3][4][5][6][7][8][9][10][11] are now available along with many relevant theoretical works. Some gave predictions before these analysis [12][13][14][15][16][17][18][19][20][21][22][23][24][25]; some helped at the interpretation of these results [26][27][28][29][30][31][32][33][34]. Let us emphasise that many of these theoretical works relied on automated tools adapted to quarkonium production.…”

Abstract. We briefly review recent results which we have obtained in the study of J/ψ+Z production at the LHC. Considering our NLO computation in the Colour Evaporation Model (CEM) as an upper theory limit for the single-parton-scattering contributions, we claim that the existing data set from ATLAS points at a dominant double-partonscattering contribution with an effective cross section smaller than that for jet-related observables. As a side product of our analysis, we have computed, for the first time, the one-loop QCD corrections to the J/ψ P T -differential cross section in the CEM.

“…We use the same notation for the terms in the Lagrangian as in our previous work [34]. For the simplified s-channel model we consider the interaction terms in the Lagrangian are of the form [35] (2021) 81: 44 Page 3 of 16 44 (1) where V denotes the vector mediator field with mass M V , χ the fermionic DM field with mass m χ , q a quark field with mass m q for each quark flavor q = u, d, s, c, b, t, and g V (A) f the coupling strength between the vector (axial-vector) mediator and fermionic particle f (with f = q, χ).…”

We present a calculation of the next-to-leading order QCD corrections for the scattering of Dark Matter particles off nucleons in the framework of simplified models with s- and t-channel mediators. These results are matched to the Wilson coefficients and operators of an effective field theory that is generally used for the presentation of experimental results on spin-independent and spin-dependent direct detection rates. Detailed phenomenological studies illustrate the complementary reach of collider searches for Dark Matter and the direct detection experiments CRESST and XENON. In the case of cancellation effects in the tree-level contributions, one-loop corrections can have a particularly large impact on exclusion limits in the case of combined $$s + t$$ s + t -channel models.
