Institute for Particle Physics Phenomenology

The standing of the research at IPPP can be quantified by analysing publications and their citation record on the hep-ph archive in the past decade. According to an analysis on the particle physics' central publication hub INSPIRE, members of the IPPP contributed about 2% of the global refereed publications on hep-ph since 2005, which obtained 2.2 times the world average of citations per paper. IPPP members authored 6.4% of highly cited (more than 100 citations) phenomenology papers world-wide and about 10% of the truly world-leading papers (more than 500 citations). In terms of quantity and quality of the publications, IPPP falls into the same category as the theory groups of other national facilities such as FNAL, SLAC, BNL (all USA), or DESY (Germany), all with around the same size and with h-indices of 100±10. CERN has about twice as many publications in the past decade as IPPP or the other groups mentioned, with an h-index of 130. It is therefore comparable to the whole of the UK.

LHC and collider physics in the Standard Model and beyond

The lead authors of two of the three multi-purpose event generators for LHC physics are IPPP staff, supported by the two Physicist Programmers. One of the three Parton Distribution Function sets (MRST/MSTW/MMHT) that are routinely used by the experiments originated in Durham and is still co-authored by one of the IPPP members. IPPP members are world-leading in the calculation of QCD NLO and NNLO corrections for processes relevant to LHC physics and in the development of numerical and analytical methods that are central for such calculations. Members of the group are deeply involved in the construction, validation and deployment of methods for LHC precision analyses, for example for multi-jet and boosted topologies. IPPP is also playing an active role in defining the physics programme of future circular collider(s). In flavour physics IPPP leads in topics of Heavy Quark Expansion and B-mixing. Flavour observables are a powerful tool to bound parameter spaces of new physics models.

Dark Sectors, Neutrinos and BSM phenomenology

IPPP members play a leading role in the construction and phenomenology of New Physics sectors, working on neutrinos and astro-particle physics, Higgs-portal models, supersymmetry and string phenomenology. The applications range from the LHC and FCC colliders at the energy frontier to neutrinos, DM detection and light-shining-through-the-wall high-intensity frontier experiments. IPPP is one of the leading institutes in the SuperCDMS collaboration, contributing the Chairman of the Science Working Group and member of the collaboration board. IPPP members are also actively involved in the ATLAS-CMS Dark Matter Forum tasked with theory support and model simulations for DM searches at the LHC Run II. The IPPP continues to lead physics studies of future long baseline neutrino facilities (e.g. Physics WP leader in LAGUNA-LBNO, ELBNF (now DUNE) LoI Writing Committee, DUNE IB) and has done seminal work on lepton-flavour violating models at LHC and key studies in neutrino-less double beta decay, sterile neutrinos, and lepto-genesis.

IPPP Phenomenology Network

IPPP is committed to serving the wider UK phenomenology community, including theorists and experimenters alike. To mutually enhance the research in the UK institutions, IPPP runs a network, including experimental fellowships and associates in addition to its workshop and visitor programme.
