Attempts to incorporate in a coherent picture the B-decay anomalies presumably observed
in b → cb→ c and b → sb→ s semi-leptonic decays have to face the absence of signals in …

We present PandaX-II constraints on candidate WIMP-nucleon effective interactions
involving the nucleon or WIMP spin, including, in addition to standard axial spin-dependent …

The ubiquity of top-rich final states in the context of beyond the Standard Model (BSM)
searches has led to their status as extensively studied signatures at the LHC. Over the past …

We introduce version 2.0 of Z′-explorer, a software tool that provides a simple, fast, and
user-friendly test of models with an extra U (1) gauge boson (Z′) against experimental LHC …

Unequal strengths of boundary localised terms lead to non-conservation of the Kaluza-Klein
(KK) parity in the 4+ 1 Universal Extra Dimensional model. Consequently the first excited KK …

In this work we analyze a phenomenologically rich four body decay Λb→ Λ (→ pπ−) µ+ µ−
which provides a large number of physical observables that can be accessed …

This thesis describes a measurement of the differential top quark pair production cross
