Designing the SND@LHC experiment

SND@LHC is a newly proposed, compact and stand-alone experiment to perform measurements with neutrinos produced at the LHC in a hitherto unexplored pseudo-rapidity range of 7.2 < 𝜂 < 8.6, complementary to all the other experiments at the LHC,…

Hunting for axion-like particles at neutrino detectors

Although neutrinos were discovered more than 60 years ago, they are the most mysterious particles in the Standard Model (SM). While the present data collected at the neutrino experiments can explain several neutrino properties, there are still at…

Beyond the Standard Model Explanations of GW190521

Earlier this month the LIGO and Virgo gravitational wave observatories announced the discovery of GW190521, an exceptional and extraordinary signal. Seven billion years ago — a little over half the age of the universe — at the other end of the…

Closing the gap between beam dump and colliders ALPs searches with NA64

The axion was postulated to provide a solution to the "strong CP" problem. This pseudo-scalar particle emerges as a consequence of the breaking of the Peccei-Quinn (PQ) symmetry [1,2,3] (link to EP article on Axions). Typically, models of QCD axions…

NA62 experiment at CERN reports first evidence for ultra-rare process sensitive to new physics

The CERN NA62 collaboration presented at the ICHEP 2020 conference the first significant experimental evidence for the ultra-rare decay of the charged kaon into a charged pion and two neutrinos (K+ -> π+νν). The decay process is very sensitive to…

How to search for new physics without knowing about it?

BSM searches at the LHC increasingly profit from ML techniques since this approach allows more general searches that minimise the probability of missing evidence of new physics. Very recently, the ATLAS collaboration has published a novel approach […

ATLAS results: from precision to rarity

 Two recent ATLAS results that showcase the full range of the ATLAS physics potential, from precision to rarity, were shown at LHCP and presented at a recent CERN LHC seminar. A test of the universality of τ and μ lepton couplings in W boson decays…

CMS tunes in searches for new physics

The CERN LHC has produced proton-proton collisions at an unprecedented center of mass energy of 13 TeV since 2015, providing an excellent opportunity to search for new phenomena in regions that were previously inaccessible to collider experiments.…
